<B>What is MilkDrop?</B>
-----------------------
<B>MilkDrop</B> is a music-visualization "plug-in" for the Winamp music player.  
As you listen to music through Winamp, MilkDrop renders the soundwaves in a 
visual feedback loop, driven by 3D graphics hardware, to create a 
rich visual journey through sound.  MilkDrop can also be driven by a live 
audio feed (microphone or line-in) - see the documentation for details.

<B>MilkDrop 2</B> is a major upgrade to the original MilkDrop visualizer, opening up 
the power of modern graphics chips and programmable pixel shaders to the realm 
of music visualization.  Pixel shaders allow dozens, even hundreds of complex 
instructions to be executed for every pixel on the screen, every frame.  
Other new features include jpg textures, gaussian blurring, a preset "mash-up" 
feature, and a prest "back" button.  MilkDrop 2 is backwards-compatible with 
presets from MilkDrop 1.

<A NAME="1">
<B>1. Requirements</B>
-----------------------
    1. Windows 98, ME, 2000, XP, or later.
    2. Hardware-based 3D graphics acceleration (i.e. a video card with 3D support)
        supporting DirectX 9 with at least 8 MB of video memory; 
        however, we strongly recommend a GeForce 5700 (or better), 
        or a Radeon 9600 (or better).
    3. Winamp 5.12 or later ( <A HREF="http://www.winamp.com/">http://www.winamp.com/</A> ).
    4. DirectX 9.0 or later ( <A HREF="http://www.microsoft.com/windows/directx/">http://www.microsoft.com/windows/directx/</A> ).


<A NAME="2">
<B>2. Installation</B>
-----------------------
    MilkDrop 2 comes with Winamp.  To install it, just download and
    install the latest version of Winamp.  During the installation,
    make sure the "MilkDrop 2" visualizer option is checked, so that 
    it gets installed, too.  

    Once Winamp is installed, launch it.  Load some music files into
    your playlist and start playing some music.  (Be sure to play some music 
    before trying to launch the visualizer - otherwise you'll just see a 
    black screen.)  
    
    Once music is playing, hit <B>CTRL+K</B> and a list of visualization 
    plug-ins will appear.  Select "MilkDrop 2" from the list.  Then click 
    the "Start" button, and it will launch the visualizer.  

    Quick Tips:    
      * If you want to go full-screen, double-click on the visualizer itself.
      * CTRL+SHIFT+K starts or stops the visualizer.
      * To configure MilkDrop's options, exit the visualizer and hit ALT+K.
    
    If you have trouble getting MilkDrop to run properly after installation, 
    try installing various recent WHQL drivers for your video card, or installing 
    DirectX; doing these two things (especially the first) will fix 99% of
    problems. See the Troubleshooting section of the documentation for more
    information. 


<A NAME="3">
<B>3. Tweaking to achieve the best image quality</B>
-----------------------
    a) Fullscreen Display Mode   [first tab of config screen]
        
        When you run MilkDrop fullscreen, it changes the display
        mode to whatever you select here.  Generally speaking,
        the speed (framerate) and smoothness of MilkDrop will drop
        as the resolution (number of pixels on the screen)
        increases.  So, if it's running to slow in fullscreen 
        mode, try selecting a smaller fullscreen display mode. 
        
    b) Canvas Stretch  [second tab]
    
        This option lets you trade resolution [crispness] for
        speed.  If MilkDrop runs too slow, in any mode (windowed/
        fullscreen/desktop), try cranking up the canvas stretch
        to, say, 1.5X or 2X.  The image will not look as crisp,
        but MilkDrop will probably run much faster.  (Assuming
        that your graphics chip was the bottleneck.)

    c) Mesh Size  [second tab]

        This is the main option that affects how much processor
        (CPU) MilkDrop uses.  If you crank it up far beyond the
        default, expect to be CPU-bound (where your framerate drops
        because the CPU is the bottleneck).  To get MilkDrop to
        speed up, drop the Mesh Size back down.  The Mesh Size 
        decides how many points on the screen the per-vertex
        equations will be executed for; the higher the mesh size,
        the more fidelity you will see in the motion.  
        
    d) tips for LCD and laptop users

        LCD screens: Note that most LCD screens (flatpanels) usually run 
        at a fixed frequency only - usually 60 Hz - meaning that they update 
        the screen 60 times per second.  However, sometimes the video driver 
        reports that it supports other refresh rates, such as 72, 75, 85, etc.  
        It is strongly recommended that [for fullscreen mode, and for Windows 
        in general] you choose a display mode with a 60 Hz refresh rate, for 
        the smoothest possible animation.  For this plugin, you will also want 
        to choose Maximum Framerates that divide evenly into 60 - such as 60, 
        30, 20, 15, 12, 10, 6, 5, and so on - so that the # of times the LCD 
        shows each frame of animation remains constant, resulting in the 
        smoothest possible animation.

    e) color (bit) depth: 16 or 32?
    
        The answer, nowadays, is a resounding "32".  Video memory
        is plentiful these days; use 32 bit color, for both your 
        windows desktop (...so that MilkDrop's windowed mode can
        run at 32 bits) and for MilkDrop's Fullscreen Display Mode
        setting (where "8888" denotes 32 bits).
        
        Some ancient video cards don't have enough memory to run MilkDrop
        properly (or smoothly) in 32 bits, though; you might want to 
        try 16-bit color if your card has less than 32 MB of video 
        memory, if you are using a laptop, or if your video card is 
        significantly old.  In the MilkDrop config panel, 16-bit modes
        show up as "555" or "565".

        If you find that your card runs best in 32-bit color, you should
        have no problems with brightness levels while running MilkDrop.
        However, if your card runs best in 16-bit color, you should 
        then adjust the Brightness slider on the second tab of the config 
        panel (which only affects 16-bit color video modes!).  The goal 
        is to make the image as bright as possible, without oversaturating 
        it (washing it out, often to bright pink or white).  This setting 
        also varies for different cards, depending on how the card rounds 
        color values, so we recommend seeing how bright you can set the 
        slider (closer to '0') without oversaturating the image.  Usually,
        a setting of '0' or '2' works the best.

            H: instant Hard cut (to next preset)
            R: toggle random (vs. sequential) preset traversal
            L: load a specific preset (invokes the 'Load' menu)
            +/-: rate current preset (better/worse)
            scroll lock: lock/unlock current preset 
                (keyboard light on means preset is locked)
                (prevents random switch to new preset)
            A: aggregate preset - loads a random preset,
                steals the warp shader from a different random preset,
                and steals the composite shader from a third random preset.
            D: cycle between various lock-states for the warp and
                composite shaders.  When one of these shaders is locked,
                loading a new preset will load everything *except* the
                locked shaders, creating a mix between the two presets.

    <A NAME="4d">
    <B>4.d. rating system</B>

        The built-in rating system allows you to rate each preset on a scale 
        from 0 to 5.  A rating of 5 is very good, while a rating of 0 is
        the worst.  The ratings decide how often the presets will be randomly
        loaded.  If a preset has a rating of 0, it will never be randomly
        loaded (unless they're all zero; then they all have an equal chance).
        
        To show the rating for a preset, press F6.  You can adjust the 
        rating for a preset with the +/- keys.  When you make adjustments,
        they save automatically; there's no need to save the preset to make
        the rating change permanent.
        
        Here's a recommended interpretation of the numeric values:
            0 = I never want to see this preset again
            1 = very ugly
            2 = mediocre
            3 = fair
            4 = good
            5 = downright stimulating
            
        If a preset seems "lost" because you set its rating to 0 and it
        won't ever come back, you can always load it up by hitting 'L'
        to conjure the 'Load Preset' menu, finding the preset you want,
        loading it, then hitting +.
            
    
    <A NAME="4e">
    <B>4.e. custom messages</B>

        ABOUT CUSTOM MESSAGES
            The "Custom Message" feature of MilkDrop allows you to display
            short text messages on the screen while MilkDrop is running.
            They are highly configurable; you can set all of the following
            parameters: the font, the size, the positioning, color, bold 
            state, italic state, and so on; and you can even have it 
            randomize some of these properties.

        CREATING THE MESSAGES
            You can save up to 100 messages in the file MILK_MSG.INI in
            your Winamp\Plugins\ folder.  To open this file, go to the 
            MilkDrop configuration screen (ALT+K from Winamp) and click the
            "Edit Custom Messages" button.  Or, you can just edit it 
            manually if you know how; it's plain-text.
            
            The first thing you see when you open the file is a bunch of
            lines that start with two forward slashes (//).  These are
            comment lines, and they explain the syntax for adding a font
            or a message to the file.  This is your main reference for
            finding out what all the parameters do for the fonts & messages;
            it is recommended that you leave this information in the file,
            although it can be removed or (modified) and the messages will
            still work.

            After the comments come first the fonts, then the messages.
            The fonts are simply a way to specify a typeface, bold state,
            italics state, and red/green/blue color for the font.  You can 
            configure up to 16 fonts like this (numbered 00-15). These fonts
            will serve as template fonts for the custom messages.

            The next section is the actual messages.  Each one has a
            text message (the 'text' parameter) that will be shown to the
            user, and each one references one of the 16 fonts that were
            defined in the previous section.  You can also specify the
            size (size), position (x,y), a growth factor (growth) that
            will grow/shrink the message over its lifetime, the number
            of seconds to show the message (time), and the fraction of that
            time that is spent fading in (fade).  

            You can also randomize some of these values: 'randx' and 'randy'
            will randomly perturb the (x,y) coordinates every time the message
            is shown to the user, and 'randr'/'randg'/'randb' will randomly
            perturb the (r,g,b) color in the same way.

            Finally, you can override any of the default properties for the
            font that this message uses: (face, bold, ital, r, g, b).

        INVOCATION AND USAGE
            There are two ways to invoke custom messages: one automatic,
            the other manual.  

            The automatic way is to go to the MilkDrop config panel (ALT+K),
            click the 'More Options' button, and set the value in the
            'Time between RANDOM custom messages' box to something greater
            than zero.  This will cause MilkDrop to randomly display custom 
            messages while it is running, and the average time (in seconds) 
            between messages will be the value you entered here.  If you 
            wish to disable random custom messages, set this value to -1
            (or any negative number).  Note that all messages in the file
            have an equal change of being picked.

            The manual way is to type in the two-digit code (00-99) of the 
            message while MilkDrop is running.  However, you can't use the 
            numeric keypad for this - you have to use the numbers at the 
            TOP of your keyboard to do it.  If you mess up while entering
            the first digit, just press the '*' key to start over.
            
            Note that if you change the MILK_MSG.INI file while MilkDrop
            is running, you will not be able to see the changes until
            you hit F7, which tells MilkDrop to re-read the MILK_MSG.INI 
            file from disk.


    <A NAME="4f">
    <B>4.f. sprites</B>

        ABOUT SPRITES
            The "Sprite" feature of MilkDrop allows you to display
            any image of your choice in the foreground (on top of 
            MilkDrop) while it runs.  The sprites can fade in and out,
            move around, respond to the music, and so on.  You define
            them in a file - <B>milk_img.ini</B> in your winamp\plugins
            directory - much like you define custom messages, each 
            having an identifying code number from 00 through 99 (used
            to invoke them).  However, the way the individual sprites
            are defined is different; <EM>you write code for them</EM>, instead
            of just setting parameter values.  This is a little bit 
            tougher to do (it's very much like preset authoring), but
            adds a great deal of flexibility to what you can do with
            the sprites.

        CREATING THE SPRITES
            You can define up to 100 sprites in the file MILK_IMG.INI in
            your Winamp\Plugins\ folder.  To open this file, go to the 
            MilkDrop configuration screen (ALT+K from Winamp) and click the
            "Edit Sprites" button.  Or, you can just edit it manually if 
            you know how; it's plain-text.
            
            The first thing you see when you open the file is a bunch of
            lines that start with two forward slashes (//).  These are
            comment lines, and they explain the syntax for creating a sprite. 
            This is your main reference for finding out what all the 
            parameters do for the fonts & messages; it is recommended that 
            you leave this information in the file, although it can be removed 
            (or modified) and the sprites will still work.

            After the comments come the sprite definitions.  Each sprite is
            made up of one parameter that indicates the image file to use
            (this is the 'img=...' line), and two types of code: initialization
            code, and regular code.  
            
            The first - initialization code - is executed only once, when you 
            launch the sprite.  Use it to do one-time initialization of variables
            (such as the opacity (a), rotation angle (rot), position (x,y),
            and so on) or to invent new variables that you will access later.
            This code is marked by the 'init_1=...', 'init_2=...', etc. lines.
            
            The second type of code - marked by 'code_1=...', 'code_2=...', etc.
            - is executed every frame, just prior to plastering the sprite on 
            the screen.  Use it to animate the sprite, moving it around (changing
            x,y), scaling it up and down (sx,sy), fading it in and out (a),
            changing its color, and so on.
            
            Please see the comments included in the sample milk_img.ini file
            for full details and examples on how to author sprites.

        INVOCATION AND USAGE
            There is currently only one way to invoke sprites: manually.
            To do this, first press 'K' to enter 'sprite mode' (while 
            running MilkDrop).  Now, whenever you type in a two-digit 
            code (00-99), MilkDrop will try to find & launch the sprite
            you've requested, from the milk_img.ini file.  If there is
            an error, it will display an error message in the upper-right
            corner.  Note that to enter the two-digit code, you can't use 
            the numeric keypad; you have to use the numbers at the TOP of 
            your keyboard.  

            If you make an error entering the first digit of the code, 
            just press '*' to start over.  If you want to
            clear the most recently-invoked sprite, press DELETE.  If you
            want to clear the oldest sprite, press SHIFT + DELETE.  If you
            want to clear all sprites, press SHIFT + CTRL + DELETE.
            
            If you want to clear sprites by their 2-digit code, press
            SHIFT + K (instead of just 'K') to enter 'sprite kill mode.'
            Now, when you enter a two-digit code, instead of invoking
            the sprite, MilkDrop clears all running sprites with that
            two-digit code.

<B>5. TROUBLESHOOTING</B>
-----------------------
    
    If MilkDrop has a critical problem (e.g. fails to load, freezes, etc.)
    or if the image is distorted, torn, corrupted, or all one solid color,
    try the following two suggestions to resolve the problem.  In 90% 
    of these cases it can be fixed.  If you have a different problem, 
    scroll down past this part and try to find the appropriate symptom 
    and its solution.

    1. UPDATE YOUR VIDEO DRIVER, OR TRY OTHER DRIVERS
    
        Almost all display problems are caused by buggy video drivers!
        
        A "driver" is a piece of software that translates graphics-related 
        commands from programs, like MilkDrop, into the native language of 
        your specific graphics hardware.

        For desktop machines, there are typically three sources for video drivers: 
            1) those from the *chip* manufacturer's website (usually 
                nvidia.com or ati.com) (best source) 
            2) those from the card manufacturer's website (LeadTEK, PNY, etc.)
            3) those that shipped with Windows (yuck)
        
        For laptops:
            1) the driver from the *laptop* manufacturer
            2) (maybe) the driver from the graphics chip manufacturer 
                (ATI, Nvidia, etc) - however, it's fairly common to find 
                that the laptop requires a custom driver written by the
                laptop manufacturer.
            3) the driver that shipped with Windows (yuck)

        Give them all a shot.  Track down every driver you can find for
        your card, and try it.  Try the WHQL ones first - these versions of
        the drivers have passed "Windows Hardware Quality Labs" certification
        and are usually the more stable and reliable ones.  
        
        In general, it's a very good idea to use only Microsoft-certified 
        WHQL drivers for your video card.  Often people want to get the newest, 
        fastest beta drivers, but these drivers are almost ALWAYS riddled 
        with new bugs.  You can also watch the version number of the drivers
        a company releases - if the version number just jumped to a new
        series (such as from the 70's to the 80's), watch out, it probably 
        has a lot of bugs that need worked out - give it 3-4 months before
        expecting the new driver series to work well.  With video drivers,
        the newest isn't always the best!

        Here is a list of some common card/chip manufacturers and where 
        to get their drivers.  Don't forget to choose the WHQL driver!
        
            [ <A HREF="http://www.nvidia.com/page/drivers.html">NVIDIA driver</A> ]
                Card manufacturers using NVIDIA (GeForce) graphics chips:

            For others - or in general - if your graphics chip is made by Trident, 
            for example, then try a <A HREF="http://www.google.com/">google</A> search for:
            
                Trident graphics driver
                        
            Then click on "support", then "drivers" (or "downloads"), then
            "graphics driver", and so on.
                        

    2. [RE]INSTALL DIRECTX
    
        Make sure you have a quasi-recent version of <A HREF="http://www.microsoft.com/windows/directx/">Microsoft DirectX</A>
        installed.  In reality, though, almost every PC in the world has
        DirectX 9 on it at this point, so this shouldn't be a problem.
        If you go to download it, you'll only be able to find DirectX 10 -
        this is fine to install, though, as it includes DirectX 9 inside 
        it.  As a last resort, though, if you are having problems,
        you could try re-installing DirectX to see if it helps.
    
    
    If you're having a non-critical problem, browse the following list of
    common problems and their causes and solutions.  Note that for each symptom-
    cause-solution block, there can be multiple symptoms with the same cause and 
    solution, and the same symptom might be listed in multiple blocks.
  
    If the solutions below don't work for you, please visit the forums at
    <A HREF="http://www.nullsoft.com/free/milkdrop">http://www.nullsoft.com/free/milkdrop</A>, where you can read the most
    recent troubleshooting issues and solutions.
        

    ENTRY 1
    SYMPTOM:
        -any error message saying "Failed to create ..." 
            or "not enough memory...", or
        -only a portion of the screen displays correctly; the rest is 
            either filled with garbage or badly flickering
    CAUSE:
        1) Your video card might not have enough memory to run MilkDrop at 
        the resolution (screen width and height) you've picked, 
        2) your drivers might be out of date, 
        3) you might need to reinstall DirectX (very very rare), or
        4) your graphics card might be to crappy to *actually* run
             pixel shaders well.
    SOLUTION:    
        1) To battle video memory problems:

            Go to the config panel and try smaller video modes (e.g.,
            320x240 is smaller than 640x480).  Even better is to try
            a lower color bit depth; if you'd selected a 32-bit ("8888") 
            video mode before, try a 16- ("565" or "555") or 24-bit ("888") 
            one, for example.  Note that it might only work in one of them; 
            so make sure you try them all.  Trying these things is especially 
            important on laptops with limited video memory, or older video 
            cards with a small amount of video memory.
        
            Finally, you can try locking the texture size (or "canvas size") 
            to 256x256 pixels, just to see if that fixes the problem.  
            If it does, try using a smaller fullscreen video mode to
            free up some memory, or if running windowed, close other
            graphics-hungry applications.
        
        2,3) for instructions on how to reinstall DirectX or update 
            drivers, <A HREF="#5">go here</A>.
            
        4) Go to the MilkDrop config panel (hit ALT+K) and on the second tab, 
            in the "Pixel Shaders" box, select "None."  Now does MilkDrop run 
            ok?  If so, your video card probably just can't reliably run
            pixel shaders, due to either inferior hardware, or it could
            be the driver.  You can always try setting "Pixel Shaders" 
            back to "Auto" and then installing a newer (preferably WHQL) 
            video driver.


    ENTRY 2
    SYMPTOM:
        -When I go to the Load Preset menu ('L') in MilkDrop, some of the
            presets on disk are missing.
        -I downloaded some new presets and put them in my Plugins\MilkDrop2\Presets
            directory, but I can't access them from within MilkDrop.
    CAUSE:
        You probably have an older video card that can't handle the pixel
        shaders needed to run some of the presets.  MilkDrop automatically
        hides any presets from you that you can't run.
    SOLUTION:
        * You could buy a new graphics card - one that meets the minimum
        recommendation for MilkDrop 2.  These cost less than $40.
        * You could try forcing MilkDrop to try to run these presets.
        Sometimes MilkDrop just hides them from you because it predicts
        they will run horribly slow on your graphics card; in case it
        is wrong about that, try this.  Go into the MilkDrop config
        panel (ALT+K) and go to the More Settings tab.  Under the 
        "Pixel Shaders" option, change it from "Auto" to "Shader Model 2"
        or "Shader Model 3".  Then try to run MilkDrop and see if the
        presets appear.  If they do, you're in luck; if they don't, your
        GPU really doesn't support those shader models.
    

    ENTRY 3
    SYMPTOM:
        MilkDrop always looks the same - it's always showing the same
        preset, and it never changes to a new preset unless I tell it to.
    CAUSE:
        Scroll Lock is on.
    SOLUTION:
        The Scroll Lock key is how you tell MilkDrop to lock the current
        preset - i.e. don't randomly transition to a new preset unless you 
        do it.  The state of the Scroll Lock key is remembered when you
        start or stop MilkDrop, too, so be careful of that.  If you are
        experiencing this problem, you can fix it in any of the following
        three ways:
          1. hit Scroll Lock while MilkDrop is running (and the viz window is active);
          2. load up the MilkDrop config panel (ALT+K), go to the More Settings
              tab, and uncheck the "Start milkdrop with preset lock (scroll lock) 
              key ON" box;
          3. if you're using a modern skin, there is a "random" button on
              the frame of the window, which is the inverse of the Scroll Lock
              state - i.e. you probably have Scroll Lock on and "random" off.
              Click the "Random" button to turn random transitions back on
              (and notice that scroll lock gets turned off as a result).
       
    ENTRY 4
    SYMPTOM:
        I was browsing for presets from within MilkDrop ('L') key and 
        got lost.  How do I get back to my presets?
    SOLUTION:   
        Two ways to fix this.  The easiest is to just reset MilkDrop
        to its defaults - hit ALT+K to load the MilkDrop config panel,
        then click the 'Defaults' button.  The next time you launch
        MilkDrop, it will start you in the default preset directory.
        
        To fix it manually (and preserve all your settings), run
        MilkDrop, hit F8, and paste in this path:
          C:\Program Files\Winamp\Plugins\Milkdrop2\presets
        [or equivalent].
        
        Another way to fix it is to hit 'L', and browse all the way 
        down to the root folder (repeatedly select ".."), then
        go into Program Files, Winamp, Plugins, MilkDrop2, and finally,
        presets.
        
            
    ENTRY 5
    SYMPTOM:
        -things flicker through (such as my AIM window ticker, taskbar
        clock, web page animations, etc.) when I'm running MilkDrop
        in fullscreen mode.
    CAUSE:
        You're probably running MilkDrop fullscreen at the same
        resolution & color depth as your desktop, and Windows isn't 
        properly handling MilkDrop's request for exclusive access to the
        screen, and is still letting other applications paint (draw)
        themselves.
    SOLUTION:
        Change either your Windows desktop resolution or color depth, or 
        MilkDrop's fullscreen resolution or color depth, so that there
        is some difference between the two.   (To change your Windows 
        display settings, go to the Start Menu -> Settings -> Control 
        Panel -> Display -> Settings tab, and then change the "colors" 
        or "screen area" settings from there.)  Also make sure you're
        not using "fake" fullscreen mode (...uncheck this box on the
        main screen of the config panel).

<B>6. Known Issues / Misc. / Tips:</B>
---------------
    a. Tip for video capture: if you'd like to save sequences of video 
        from this plugin, there are several programs out there that will 
        let you do this.  Warning: you will need a ton of free hard drive 
        space, and a fast CPU helps.  A few of these programs are:
            "FRAPS"               <A HREF="http://www.fraps.com/">http://www.fraps.com/</A>
            "Hypercam"            <A HREF="http://www.hyperionics.com">http://www.hyperionics.com</A>
    
    b. Close other apps:
        For the best graphics performance, try to close as many other 
        applications as you can, before running the plugin, especially 
        those that tend to work in the background, such as anti-virus 
        or file-swapping software.  Also, if you must leave other 
        applications open, try to minimize them (i.e. shrink the window 
        down to the taskbar) so that they stay out of the painting loop.
    
    c. Windows Vista / Winamp with per-user settings
        Be aware that if you're running Vista as a non-admin user,
        you can't write to (or delete from) files in the Program Files
        directory, which is were MilkDrop 2 is installed.  So, anything
        you try to write or save (like milkdrop's settings file, milk2.ini; 
        or presets) will probably end up deep in some user-specific, 
        virtualized "Program Files" directory somewhere on your hard 
        drive.  Yell at Microsoft for this one!
        
        Also, if you installed Winamp with per-user settings (instead of 
        shared settings) - on any OS, not just Vista - be aware that your
        .INI files (milk2.ini, milk2_img.ini, milk2_cfg.ini) are all
        stored in a folder like this:
            
            C:\Documents and Settings\<username>\Application Data\Winamp\Plugins         
            
        (Note that 'Application Data' is a hidden folder.)  However,
        presets, textures, and things like that are all shared between
        users, in the real [c:\Program Files]\winamp\plugins\milkdrop2 folder. 
        If you want to keep your presets separate, you can still do that, 
        though - just put them in a personal folder, and then seek to it
        from within MilkDrop.  If you're using per-user settings in Winamp,
        it will remember which folder you last used.
        

<A NAME="7">
<B>7. Using Line-In</B>
-----------------------
    If you want to use your sound card's Line-In or CD Audio inputs for
    sound data (instead of mp3 files), you can do this.  Do the following:
        1. CONNECT WIRES
            Connect your audio source (a stereo, a live feed, whatever) into
            the line-in (or microphone) 1/8" jack on your sound card.  You
            might want to test & verify that your cable is good before doing 
            this.
        2. SELECT SOUND INPUT CHANNEL & ADJUST VOLUME
            In Windows, double-click the speaker icon in your systray (where
            the clock is).  Then, on the menu, go to Options -> Properties
            and select the "Recording" option.  Then make sure the Line In
            (or Microphone) input channel (whichever is appropriate for
            your case) is SELECTED (with a check mark) and that the volume 
            is close to, or at, the maximum.  Hit OK.           
        3. TELL WINAMP TO USE LINE-IN
            Open Winamp, and hit CTRL+L (the "Open Location" hotkey).  Now
            type in "linein://" as the location you want to open.  (Leave out
            the quotes and make sure you use FORWARD slashes.)  Hit PLAY
            ('x' key for the lazy), and the little built-in oscilloscope (or 
            spectrum analyzer) in Winamp should start showing your signal.
        4. RUN MILKDROP
            Run MilkDrop as usual.  If the waves are too small or large, 
            either adjust the volume from Windows' Volume Control, or adjust
            the sound level at the source.       
   
    If you are doing shows using live audio, and if you have a multiple monitor
    setup, you might also want to use the "VJ mode" feature, which lets you 
    control MilkDrop (even editing shaders on the fly, etc.) via a separate monitor.

<A NAME="9">
<B>9. Version History</B>
-----------------------
2.2 - November 2009
    - updated to use ns-eel2 (thanks Justin)

2.1 - January 2009
    -pixel shader 2.0 & 3.0 support tweaks
    -unicode support for F2 key feature
    -removed some older Milkdrop presets and added some newer ones to Winamp installer

2.0e - August 2008
    -added localization support    
    -unicode support for milkdrop playlist and title    
    -tweaked menus

2.0d - January 2008
    -worked around colossal Intel driver bugs.  See (or skip) long description in next item.    
    -tightened up various uses of the DX9 api, to decrease the chances of bugs due to poor DX9 compliance
        by drivers for lower-end graphics chips (namely Intel integrated graphics).  Most importantly,
        all Intel drivers seem to implement DrawIndexedPrimitiveUP() incorrectly, which was killing
        MilkDrop.  Since Intel has has this collosal failure in their driver for eons, I decided to work
        around it, and removed all calls to this function.  MilkDrop should now run properly on Intel
        graphics chips.
    -also did the following little things to help decrease chances of buggy driver interactions:
        -now using more exact D3DFVF_TEXCOORDSIZE2(0,1,2) specifiers, in addition to _TEX2, etc.
        -cleaned up headers (vertex declarations) in data\*.fx files to more closely match the vertex buffers.
        -set z==0 for all vertices during the composite shader
    -fixed some bugs w/giant mesh sizes

2.0c - December 2007 (bundled with winamp 5.51)
    -if a texture (used in a shader) is not found, MilkDrop now also looks in the current preset folder
        to try and find it.  This makes it so that preset downloaders can be lazy and just put 
        the presets, along with the textures that come with them, into the same directory.
    -fixed a bug where blur textures weren't always being sampled with bilinear filtering
    -fixed a bug where it would sometimes crash when exiting fullscreen mode while using a modern skin
        (needed to tell Winamp that we were the viz window, via SET_EMBED_GUID(avs_guid))
    -desktop mode no longer causes explorer to crash in Windows Vista; it instead just shuts 
        off the icon-re-creation code.
    -desktop mode: fixed default placement of icons, when taskbar is on the left/top side of the screen.
    -removed Winamp version check, so people can run it with older winamps (within reason)
        -if warand() function can't be found (older winamps), it calls a wrapper fn to rand()
    -fixed font face for custom messages - was errantly using song title font face for custom msgs
    -song title texture size is now based on max of screen width vs. height, rather than just width.
    -simple waveform no longer draws itself when its alpha is less than 1/256 (0.004).
    -added some cool new presets / filtered out some old crummy ones & repeats
    -changes of note for preset authors:
        -added "pixelsx" and "pixelsy" to preset's main per-frame and per-vertex equations. 
            (equiv. of "texsize.xy" in shaders)
        -custom waves: you can now vary the # of samples from the custom wave per-frame code.
            Added new var, "samples", to custom wave init code [read only] and per-frame code [r/w] - 
            tells you (and lets you set) the # of samples to draw for the wave.
        -'time' value in shaders now wraps back to 0, after 10,000 seconds spent on a preset 
            (to avoid precision jitters)
        -fixed bug where 'Draw Thick' was never working for custom waves.
        -added "#define tex3d tex3D" to include.fx
    ---( changes after this point were made in v2.0a, 25 Oct 2007, which wasn't officially released... )--- 
    -Preset list scan (when milkdrop launches) now happens in a background thread, 
        so there is no drop in framerate while the scan is done.
    -added instancing to custom shapes!!
        -you can now set the # of instances for each of the 4 custom shapes
           [1..1024]
        -the per-frame code will actually be called 'num_inst' times,
           and each time, the variable 'instance' will increment (0,1,2,... num_inst-1).
    -lots of new presets
    -plugin no longer has a taskbar icon when running in desktop mode
    -shader writing: tex2d() now works (before only tex2D() worked)
    -fixed default fullscreen display mode (...if you'd never gone to the config
        panel and saved your settings, it defaulted you to 1024x768; now it
        defaults you to your desktop res).
    -fixed a few blending bugs (and greatly cleaned up the code) 
        for transitioning between presets with mixed pixel shader versions
    -transitions: when booleans from the old comp shader interpolate 
        during a blend, if the old & new shaders did & didn't use a comp shader 
        (or vice versa), then it will now be smart about when it switches the 
        boolean, so you don't see any avoidable jumps.  (mostly for darken, 
        video echo orientation, brighten, solarize, etc.)
    -presets now save with a few less decimal places for most of the values (less waste)
    -finally fixed seldom-seen wave bug; it was due to per-frame code "wave_mystery = time*0.03;" when used with wave types 0,1,4.  Now those wave types repeat the waveparam value in the [-1..1] range, so it always looks good.
    -fixed preset list selected pos after preset delete
    -found and fixed bug with custom wave/shape import
    -Fixes to documentation, driver link updates, etc.
    -Fixed bug with the 'texture wrap' and 'sustain level' menu items'
        visibility (...they should, and now only do, show if the current preset 
        doesn't use pixel shaders).
    -fixed bug with 'edit sprites' and 'edit custom messages' buttons on the config
        panel - they were trying to edit the milkdrop 1.0 ini files (milk_*.ini 
        rather than milk2_*.ini). 
    -fixed bug with desktop mode - when paused, if you dragged the mouse around
        on the desktop, milkdrop would update [new] frames instead of just redrawing
        the exact same last [paused] frame.
    -fixed bug with desktop mode - if you made winamp run just in the systray,
        then ran MD2 in desktop mode, then minimized winamp to the systray,
        then used a global hotkey to pause the song, then clicked on some
        random window (say, calc.exe) and then clicked back on milkdrop,
        the taskbar would disappear.  This no longer happens because the
        viz window, in desktop mode, now only covers the visible portion
        of the desktop, and not the area occupied by the taskbar.
    -docs: updated links & text for drivers section
    
2.0 - 10 October 2007 (bundled with winamp 5.5)
    -MilkDrop has been upgraded from DirectX 8 to DirectX 9.
    -This means it now supports Pixel Shaders.
      -Each preset can now have two shaders in it: a warp shader
        and a composite shader.
      -The "warp" shader performs the frame-to-frame image-warping operation.
      -The "composite" shader performs the final display of the feedback
        image to the user.  
      -See the <A HREF="milkdrop_preset_authoring.html">preset authoring guide</A> for more information.        
    -Added a "back" button for presets!  You can now use the 'backspace' key 
      to go back to up to 64 presets that recently played.
    -Presets can now load textures (jpg, png, etc.) from disk and use them
      (in shaders) for whatever they want.
    -Also added several built-in 2D and 3D procedural noise textures.
    -You can edit the warp & composite shaders on-screen.  
    -Per-pixel equations have been renamed to per-vertex equations, because
      that's what they really were.  These equations determine how each point
      moves - on a big grid that covers the screen.  For all the pixels in between,
      the motion was interpolated.  Now, that motion data comes into the warp
      shader as a "uv" coordinate, and you can use it like before, or you can
      do more work on top of it - but because the pixel shader truly executes
      (independently) on each pixel, the warp shader truly operates at a "per-pixel"
      resolution.
    -When editing per You can now copy and paste to and from the *Windows* clipboard.
      CTRL+C copy
      CTRL+X cut
      CTRL+V paste
		-The internal canvas (texture) size is no longer locked to power-of-2 squares;
			it can now match the window size perfectly (...or you can override it
			to use the old NP2 method).
		-Max gridsize is up from 128 to 192.
		-Added 'A' key (aggregate) - loads a random preset, then loads the warp shader 
		  from another random preset, and then loads the composite shader from
		  a third random preset.
		-Added 'D' key - cycles between various lock-states for the warp and
      composite shaders.  When one of these shaders is locked,
      loading a new preset will load everything *except* the
      locked shaders, creating a mix between the two presets.
    -Ditched 'stereo 3D' mode.  It never worked that well anyway.
    -Added "aspectx" and "aspecty" (read-only) to per-frame and per-vertex variables,
      to help presets deal with widescreen display modes properly.
      Multiply an X,Y coord by these to make it fit the window properly.
    -The q1-q8 variables have been expanded; the range is now q1-q32.
    
1.04L - 04 May 2007	
        -added localization support
        -fixed Milkdrop DEP incompatibility
        -fixed theming of preferences under XP+
	   
1.04d - 13 February 2007
        -fixed some multi-user issues 
		
1.04c - 21 June 2006
        -added missing files to Winamp installer
        -added multi user support
        -fixed 100% cpu usage when paused
        -added over 200 new Milkdrop presets to Winamp installer!


1.04b - 10 October 2003
        -slimmed down the presets for bundling w/Winamp 5
        -fixed blurry text when running in wa5 w/skinning, 
            before first window resize
        -can now start plugin w/o music (Winamp 5+)
        -(hopefully Justin shrank the DLL some, too)

1.04 - 31 July 2003
        -upgraded to VMS (VisMegaSDK) 1.05 and DirectX 8.  That means a revolutionized 
            Desktop Mode, better driver support, better multimon support, winamp
            skinning (when running in windowed mode), increased general stability, 
            and much, much more.
        -added CUSTOM SHAPES and CUSTOM WAVEFORMS.            
        -added the following variables for per-frame scripting: (all booleans, except 
            'gamma') wave_usedots, wave_thick, wave_additive, wave_brighten
            gamma, darken_center, wrap, invert, brighten, darken, solarize
            (also, note that echo_zoom, echo_alpha, and echo_orient were already in there,
             but weren't covered in the documentation!)
        -added 'meshx' and 'meshy' [read-only] variables to the preset init, per-frame, 
            and per-pixel equations
        -cranked max. mesh size up to 128x96
        -added alphanumeric seeking to the playlist; while playlist is up,
            you can now press A-Z and 0-9 to seek to the next song in the playlist
            that starts with that character.  SHIFT+A-Z seeks upward (while lowercase/
            regular a-z seeks downward).
        -added some options to config panel
        -sprites & custom messages: added 'kill' keys
            -CTRL+K kills all running sprites
            -CTRL+T kills current song title anim
            -CTRL+Y kills current custom message
        -sprites:
            -for sprites, color key can't be a range anymore; it's
                now limited to just a single color.  'colorkey_lo' and 
                'colorkey_hi' have been replaced with just one setting, 
                'colorkey'.
            -also, behavior of the 'burn' variable has changed; now,
                a sprite can be burned in on any frame, not just on the
                last frame before it dies.  See the sample sprite config
                file, milk_img.ini, for more information.
        -preset ratings are no longer read in all at once; instead, they are scanned in
            1 per frame until they're all in.  This fixes the long pauses when you switch
            to a directory that has many hundreds of presets.  If you want to switch
            back to the old way (read them all in at once), there is an option for it
            in the config panel.
        -internal texture size now has a little more bias toward a finer texture, 
            based on the window size, when set to 'Auto'.  (Before, for example,
            to reach 1024x1024, the window had to be 768x768 or greater; now, it
            only has to be 640x640 (25% of the way there).  I adjusted it because
            before, at in-between resolutions like 767x767, it looked very grainy;
            now it will always look nice and crisp, at any window size, but still
            won't cause too much aliasing (due to downsampling for display).
        -..and much many massive amounts of more!

1.03 final - 19 June 2002
        -fixed bug with motion vectors; when there were 64 of them on X
            and 48 and Y (the upper limits), stray lines would sometimes
            be drawn along the top and right edges of the screen.
        -revamped the help screen
        -added some cool new presets
        -touched up the documentation

1.03 beta 3 - 15 May 2002
        -letter 'g' no longer gets cut off in custom messages
        -(oops... it's 'wave_mode', not 'wave_type'.)
        -fixed 'q1'..'q8' in the preset init code.
        -revamped the way presets are loaded & blended; transitions
            should be cleaner now.  
        -made motion vectors morph more smoothly during transitions;
            if the old preset had motion vectors on but the new one
            doesn't, then the #, drift speed, length, and color 
            of motion vectors does not change as they fade out; 
            and vice versa if the mv's are fading in.
        -added optional 'burn-in' for sprites, so when they are finished, 
            they leave an imprint in the background.  The sprite will
            burn into the background at the end of its lifetime 
            if the variable 'burn' is set to a nonzero value; if 'burn'
            is zero, the sprite will not burn in.
        -motion vectors: reverted to 1.02 functionality, following 
            krash's advice.  So mv's should now be backwards-compatible 
            (with 1.02 versions and earlier).  Now, dx and dy are constant
            offsets for the motion vectors; if you want them to scroll,
            alter dx and dy based on the time (or frame).
        -finished writing critical notes in milk_img.ini.
        -revamped the keyboard interface for custom messages & sprites.
            see the documentation.  The realtime help screen won't
            provide too useful, though (not enough space to lay it all
            down there).
                
1.03 beta 2 - 1 May 2002
        -preset comments are in; start them with '//' anywhere on the line,
          and the rest of the line will be ignored.
        -added variables:
            -fps (read-only)
            -video echo options: echo_zoom (0..1..+inf), echo_alpha (0..1), 
                echo_orient (0,1,2,3)
            -motion vector drift: mv_dx, mv_dy (a la geiss)
            -wave_mode[0-7], wave_a(0..?)
        -fixed texel alignment
            -nVidia: dx|dy += -1/(texsize*2)    
            -same for:         http://forums.winamp.com/showthread.php?threadid=83401 
                All nVidia Cards (Many confirmed tested), 
                3dfx Voodoo Cards (Voodoo 3 confirmed tested), 
                ATI Cards (ATI All-In-Wonder confirmed Tested) 
                Kyro II Confirmed Tested 
                even Illusion's antiquated Intel Card needs it. 
            -(untested: the matrox cards)
            -super thanks to Rovastar for researching & cracking this one
        -added option for thicker waves; see wave menu.
            -note: only takes effect when texture size is >= 512x512!
        -modified presets for new texel alignment fix:
            -Zylot - Tunnel of Illusion
            -Zylot - S. Pulse Virus
            -Most of Krash' s presets
            -Illusion and Rovastar - Grand Odyssey Mod
            -Unchained: Goo Kung Foo and Perverted dialect.
            -optimized some, thanks to Rovastar for pointing out lines in
                per-pixel code that could be migrated into per-frame code.
            -many of my own: made waveforms thick
        -some new presets
            -(bipolar 4,5; supernova 2; calligraphy; others from milkdrop.co.uk)
        -fixed bug with sound analysis where sound variables in expressions
            (bass, bass_att, treb, etc.) could be NAN on the first frame
            that milkdrop ran.  (symptoms could be bad if the value was
            used over & over in subsequent frames!)
        -saved about 100k on the installer by updating to NSIS 1.98 and
            using the new bzip2 compression. (thanks again to rovastar)
        -made the texture used for song titles & custom messages take 1/4
            as much video memory (was square before, blech - now it tries
            4:1; if that fails it tries 2:1; then 1:1 as a last resort.)
        -added config panel option to mute all errors/warnings that might 
            appear in the upper-right corner.
        -revamped the configuration for desktop mode w/software blit.  
            Now, you have a choice of 3 different ways to bring the image 
            across the bus (from video to system memory).  Then the image
            is converted from RGB to YUV on the cpu, and then you also get
            to select how to send the image across the bus again, back to
            video memory, for display on the desktop.  The 3 methods are
            1) copy the data using an mmx-accelerated memory copy routine
                (never-fail cornbread)
            2) use directx to blit from one surface to another 
                (sometimes drivers flake out on this)
            3) skip it; read/write directly to/from video memory
                (never-fail cornbread)
            Regarding 1 vs. 3: they'll both always work; usually #1 is
            faster going from video to system memory, and #3 is faster
            going from system back to video; but not always.  Try different
            combinations out on your card and see what happens.
        -sprites!
            users can edit 'milk_img.ini' and write their own code to control
            the sprites.  Each sprite is an instance of a jpeg image from disk,
            displayed according to the code in the .ini file.  Up to 16 sprites 
            can be running at once.  
        -stole Y + K keys for use with custom messages & sprites.
            Hit 'y' to enter custom message mode, then enter two-digit
            codes to launch custom messages.  Hit 'k' to enter sprite
            mode, then enter three-digit codes to launch sprites.
        -added 'preset initialization code', so you can initialize
            your custom variables when the preset is first loaded.
        -increased number of 'q' variables from 5 to 8.  (q1..q8 are
            used to carry values from the per-frame equations to the
            per-pixel equations.  Note that they can now also carry
            values from the preset init equations, on to the per-frame
            AND per-pixel equations!)
		-automated the brightness slider in the config panel; now there's
			a checkbox that says, 'guess, based on my video card'.  Currently,
			the auto-brightness algorithm is simple: if you have an nVidia
			card, it will set it to 2; otherwise, it sets it to 0.
        
1.02 - 2/7/02
        -added CUSTOM MESSAGES - you can edit them in the file MILK_MSG.INI in your
            WINAMP\PLUGINS directory.  They are displayed by either keying in their
            2-digit numerical code ('##') at runtime, or randomly if you choose this
            option from the config panel (see the 'More Options' dialog).
        -also added RANDOMIZATION FOR SONG TITLE ANIMATIONS (also see the 'More 
            Options' dialog from the config panel).
        -added INSTANT HARD CUT HOTKEY: 'H'
        -for preset authors:
            -per_frame and per_pixel code use to get cut off if they didn't fit 
                on the screen; this is now fixed (flips to next page as needed)
            -when editing per-frame/per-pixel equations, the line that the cursor 
                is on is now highlighted!
            -fixed an old bug where if the per-pixel or per-frame code had nothing 
                in it except spaces & linefeeds, it would display an error message 
                saying "error in per-{pixel|frame} code".
            -added a 'trail length' parameter to the motion vectors. 
            -added a bunch of per-frame variables to control the motion vectors: 
                mv_x, mv_y, mv_l, mv_r, mv_g, mv_b, mv_a.  Also got rid of the 
                motion vectors on/off setting; now the opacity controls this.
            -cranked up max. # of user variables from 23 to 33.  (Added 16 slots, 
                but used 6 of them for motion vectors.)
            -added a per-frame variable called 'monitor'.  Set the value of this 
                variable in the per-frame code, and then press 'N' to monitor (show) 
                its value in the top-right corner of the screen.  Should be very 
                useful for debugging.  (Thanks to Krash for the great suggestion 
                on how to implement this!)
            -added the int() function, which turns the argument into an integer 
                (whole number).  Rounding is toward zero.  Examples: 
                    int(-1.1) -> -1, int(-1) -> -1, int(-0.9) -> 0;
                    int(0.9) -> 0, int (1.0) -> 1, int(1.1) -> 1;
                    int (2.1) -> 2.
        -improved 3D mode:
            -drastically improved quality of stereo 3D images by changing default 
                3d colors to CYAN (full green + blue; was just full blue) for the 
                left eye and RED for the right eye.  It turns out that this provides 
                an equivalent 3d image, but gives you the full range of colors for 
                all presets, which in turn probably makes the 3Dness more visible 
                to your brain anyway.
            -also, when in 3D mode, made the waveforms 60% white and 40% their 
                original color (used to be 100% white because so much color was lost 
                in the green channel).
        -song titles:
            -(added randomization, as mentioned above)
            -improved max. resolution of song titles by increasing the max. 
                allowable GDI font size
            -fixed longstanding bug with the "burning in" of song titles after 
                they're done displaying; the old, floating location wouldn't exactly 
                match where the title would be burned into the background & melt away.
        -timing & animation:
            -protected against milkdrop's animation running super-fast because the 
                clock jumped way ahead when no frames were rendered (i.e. milkdrop 
                got stalled somehow).
            -smoothed the animation by assuming the time for each frame to be 80% 
                of 1/fps and 20% the actual time reported.
        -misc:
            -converted ANSI_CHARSET to DEFAULT_CHARSET in CreateFont() calls (should 
                fix some display of funky/foreign character sets)
            -added 'R' key to toggle random vs. sequential order for loading presets
            -fixed alphanumeric sorting of presets (used to have minor errors such 
                as putting "galaxy 2" before "galaxy", and so forth - unfortunately 
                this is how strcmp() - even Windows Explorer - sorts them.  I rewrote 
                strcmp() to make it sort in a more 'natural' order.)
            -'&' characters in preset filenames no longer show up as an '_' character, 
                although it still looks funny if you try to save one with an '&' already 
                in it, but don't worry, it will preserve the '&' (even though it looks 
                messed up).  Note that you still can't type a *new* '&' into the filename 
                when you go to save a preset.  It is safe to rename it from outside 
                MilkDrop, though, and use it in MilkDrop later. 
            -fixed preset-to-preset blending bugs for the 10 border variables.
            -fixed a bug in blending from a preset using waveform #7 (two horizontal 
                waveforms) to waveform #0 (a circular waveform), where the right edge 
                of the top horizonal wave would get connected (via a straight line) 
                to the left edge of the bottom horizontal wave, as soon as the blend 
                began.
            -m_debug.txt: added some caps detection info at init time; screened out 
                logging of WM_MOUSEMOVE, WM_NCHITTEST, and WM_SETCURSOR messages.
            -improved motion vector motion prediction so that the tips of the motion 
                vectors should be perfectly matched from frame to frame, when the 
                trail length is set to 1.  **Note that it defaults to 0.9, so that 
                the look is similar to the old, mismatched version! (so the presets 
                are backwards compatible.)  **Also note that for video cards that 
                do not support anti-aliased edges, there could be up to 1 pixel of 
                error here.  Check m_debug.txt for whether or not your driver/card 
                supports anti-aliased edges for lines.)

1.01 - 12/7/01
        -playlist feature ('p' key) no longer crashes on Windows ME/98SE.
        -fixed problems with ampersand ('&') character in song titles/playlist
        -fixed bug with previous max. of 23 user variables per session.  (Now, 
            it's a max of 23 user variables per preset, as it should be.)
        
1.0 - 10/30/01
        -added a section to the documentation on using "line-in" as your 
            audio source (instead of mp3's)
        -lowered minimum frame time (enforced by winamp) from 25 ms to 10ms, 
            so now, the max. possible fps is 100 instead of 40.
        -tightened A/V sync by 5 ms (raised audio latency from 25 to 30 ms).
        -fixed &'s in song titles (as displayed when you hit F2)
        -F7,F8 were switched in the help screen (F1)
        -when running in desktop mode, if you have a pattern on your windows 
            background, it gets nuked.  Before, if you had a pattern, the 
            pattern would remain and you'd only be able to see milkdrop through 
            the small boxes of your desktop icons' background text.  I didn't 
            bother restoring the pattern upon exit because I am lazy and assume 
            that nobody intentionally uses these things anymore.  =)
        -improved warning message for windowed/desktop modes, when auto-texture-
            size is scaled down due to insufficient video memory.  It previously 
            just reported the downsizing, but now, it also recommends that you 
            drop your color depth to 16 bits (if you haven't already) and that 
            you try decreasing your screen resolution.
        -might have fixed a bug with the playlist feature ('p') crashing people's 
            machines.

0.99g - 9/11/01
        -added playlist browsing (hit 'p')
        -added checkbox to fix slow text (finally!)
        -song titles fixed too (on some cards, they were garbled) (also, in low 
            video mem. situations, they might have never appeared - that's fixed too)
        -added checkbox to allow double buffering for desktop mode; default is 
            UNCHECKED; can provide significant speed boost, but you might see some 
            tearing during the vertical retrace; if so, enable double-buffering.  
            It used to always be double-buffered, which is slower, though it is 
            page-tearing-artifact-free.
        -added always-on-top option for windowed mode
        -added "page x of y" footnote to the preset and playlist menus
        -improved the auto-texture-size management code, so users will be less 
            likely to get the "couldn't create offscreen surface #1" (or #2) error.  
            Instead, the textures are continally downsized until there is enough 
            memory for them.  This might mean blockier images, but at least it will run.
        -desktop mode can now do software blit when an RGB overlay surface is created. 
            (before, software blit was really only available for YUV-type overlays.)
        -desktop mode compatibility improved: more likely to work at higher resolutions now
        -desktop mode: fixed YUV-type *non-mmx* software blits when Windows is in 16-bit color.  
            (weren't implemented before; it just assumed windows was in 32-bit color, 
            and the result would look munged.)
        -improved mmx memcpy: will now copy as long as the (difference between two 
            pointers) % 8 is zero.  (before, they both had to be a multiple of 8).
        -reorganized the config panel; nice
        -centered the config panel on the screen (by removing winamp as hwndparent - der)
        -centered the 3 color picker dialogs (by specifying current dialog window 
            as the parent - der)
        -(also cleaned up redundant code for color picker dialogs)
        -super-slight optimizations to speed of waveform blending
        -tweaked the way the "clear screen at startup" option works, since some 
            users had problems with it
        -fixed aspect ratio, so when window is at an extreme AR, it clips the extra 
            (instead of fitting the image to the window)
        -fixed a fullscreen lost surface bug introduced in 0.99f that blacked 
            the screen out if you ALT-TABBED out of milkdrop & returned.
        -fixed bug where tooltips were lost on some systems (left variable in, 
            but no way to change it - locked to TRUE for now)
        -fixed bug where 'try for RGB overlay...' and 'try for YUV overlay...' 
            checkboxes were disabled when software blit was on.  (Don't know what 
            I was thinking there!)
        -tweaked presets; added some cool shift-on-beat effects

0.99f - 8/22/01
        -added graphical song titles
        -added screen borders; can be used to create interesting feedback patterns when 
            zooming out
        -waveforms now blend smoothly!
        -finally gave milkdrop an application icon
        -added 'U' key to toggle winamp's shuffle feature on/off
        -fixed bug with handling of 'r' key when preset menu is up; now, to rename a file, 
            use INSERT
        -fixed a 1-frame-delay bug for warping (caused a lag for audio-driven 'warps')
        -fixed bug where 'progress' variable's value was always 0 in per-pixel eq's 
            (thanks rovastar)
        -removed "F7: show tooltips for menu items" hotkey (needed it for title animations)
        -removed U, I keys (for warp)
        -moved T key (for zoom) to I (i=zoom in, I=zoom out) (T is now used for song titles)
        -speed optimization: now using memcpy_MMX to copy 576*2*4=4608 bytes of sound data 
            per frame
        -size optimizations: painstakingly shaved 8k off the .dll
        -in windowed mode, when a user resizes the window to a size that's too large and 
            there's not enough video memory and MilkDrop closes, it now resets the size 
            of the window for the next time you run MilkDrop.  (before it would just try 
            to start the next time with the same window position/size and keep failing.)
        -added 'try for RGB overlay before trying YUV-types' checkbox
        -added 'try for YUY2 overlay surface before trying UYVY' checkbox
        -added "stereo 3d always on" option (unchecked by default)
        -added "clear screen at startup" option (checked by default)
        -made soft cut timer reset on hard cuts

0.99e - 7/5/01
        -added beat-driven HARD CUTS; very cool
        -added a VJ mode, where you can make all the text draw in a separate 
            window instead of to the main graphics display; should be very 
            handy for concerts
        -added preset rating; use + and - keys (volume control is only available 
            w/up,down arrows now); use F6 to show rating of current preset
        -you can now use any color lenses for left/right stereo vision; just tell 
            it what color you've got (by speaking aloud)
        -desktop mode optimization: block copy from video memory is now optional, 
            because on 5-10% of systems, it actually makes things slower.
        -transitions between 2 presets both using video echo, but in different 
            orientations, are now smooth
        -added 'progress' variable to per-frame and per-pixel equations; tells you 
            how far through the preset you are (temporally) (0..1), so you can make 
            gradually-shifting effects
        -added mystery param to per-frame eq's (variable name is 'wave_mystery')
        -settings such as showing song titles, times, fps, ratings, tooltips, etc. 
            are all now preserved from session to session
        -when Load menu is up, added seeking by typing in first char of name
             -also disabled left/right arrows when Load menu is up, so music 
              won't skip on you
        -windowed mode now remembers the window's final size, position between sessions
             -safe for 2nd monitor, too
        -fixed bug with ALT-TABBING in and out of fullscreen mode
        -fixed bug with vertical spacing of song title/time readout when the fancy 
            font size was set to anything but "normal"
        -plugin listing (in Winamp prefs screen) and the window title now show the 
            version #
        -fonts now scale with the window
        -protected against trying to run MilkDrop while the config panel is still open
        -fixed the 1-pixel-wide garbage that sometimes sat at the right and bottom 
            edges, in windowed mode
        -fixed bug where after going to another app, fullscreen, while in Desktop Mode,
            upon your return from fullscreen the overlay surface was lost (and just sat 
            there, black).
        -stopped sending WM_KEYUPs to Winamp (oops; never sent WM_KEYDOWNS to begin 
            with anyway)
        -load menu: '[..]' now reads '[..] (parent directory)'
        -config panel: broke some stuff off into a 'more options' dialog

0.99d - 6/5/01
        -desktop mode is officially in
        -added new waveforms
        -added temporal wave alignment
        -added fps limiting
        -added "view documentation" button to config panel
        -added UP/DOWN keys for volume up/down
        -improved seeking for CTRL-LEFT, CTRL_RIGHT: now seeks by breaks between groups of 
            alphabetic characters, instead of just looking for spaces.
        -added 5 new variables (q1..q5) for passing values from the per-frame to the per-pixel 
            equations (user-defined variables don't carry over like permanent variables)
        -added brighten (square root), darken (square), invert, and solarize filters
        -tweak: made transitions slightly sharper (10% more toward a cosine curve than a 
            linear curve now)
        -now setting D3DRENDERSTATE_SHADEMODE to D3DSHADE_GOURAUD (used to be FLAT, 
            and combined with per-vertex coloration, which seemed to be asking for trouble)
        -added warning messagebox for if first call to SetRenderTarget fails
        -fixed bugs with the values of "x" and "y" for per-pixel equations
                -x: range was -1..1; should have been 0..1
                -y: range was 0..2; should have been 0..1
                -(all presets using x,y in their per-pixel equations had to be adjusted)
        -fixed bug where if the previous preset folder disappeared, you couldn't hit 'L' 
            to browse to a new folder
        -fixed a potential bug with dither not being a hardware capability
        -fixed a bug with scroll lock (didn't reset the LED state when MilkDrop started)
        -fixed a bug with loading presets with blank lines in the per-frame or per-pixel 
            equations
                -(the blank line, and everything after it, would not be read in)
        -revamped gamma loop

0.99c - 5/21/01
        -added red-blue stereo; use F9 to toggle it on/off
            -note: you need those cheesy glasses with the red & blue plastic 
             lenses for this to work!
        -added a bunch of 3D presets in the \3D subdir
        -added the ability to browse the directory structure
        -added F8 to jump to new directory (or drive)
        -changed the 'fix pink/white color saturation artifact' checkbox
            into a simple brightness slider, so you have more freedom with it
        -"+", "-" keys now work for the numeric keypad and regular keys.
        -fixed a video memory leak for windowed mode (the manually-created backbuffer wasn't 
            being released; once you exited winamp, though, the memory was freed)
        -fixed a bug with closing Winamp while milkdrop was running in windowed mode
        -fixed a weird bug with hitting ESC from the config panel sometimes doing nothing
        -fixed a weird bug where when milkdrop was launched in windowed mode, 
            keystrokes to winamp don't work until you moused-over the winamp window

0.99b - 5/16/01
        -added windowed mode
        -added +/- keys for volume control
        -added SHIFT + left/right arrows to rewind/ffwd 30 seconds
        -improved various error messages
        -protected vs. running config panel while MilkDrop is running
        -protected vs. running milkdrop without music playing

0.99 - 5/11/01
        -first version
