LauncherSplash.dll - plug-in that lets you throw
up a splash screen in NSIS installers with
fading effects (win2k/xp) and transparency.
Designed specially for application launchers,
when the launched application creates it's main window,
the splash screen fades out.
At the same time can play wav-mp3 sound file.

Usage:

1)   launchersplash::show [/NOUNLOAD] ClassName DelayMin DelayMax FadeIn FadeOut KeyColor [/BANNER] [/PASSIVE] [/NOCANCEL] FileName

ClassName - When launched later program creates a window of this class, image will be hidden
DelayMin  - minimal time (milliseconds) to show image
DelayMax  - maximal time (milliseconds) to show image
FadeIn    - time to show the fadein scene
FadeOut   - time to show the fadeout scene
KeyColor  - color used for transparency, could be any RGB value
   (for ex. R=255 G=100 B=16 -> KeyColor=0xFF6410),
   use KeyColor=-1 if there is no transparent color at your image.
   If KeyColor=-2 and image type is gif, plug-in attempts to extract
   transparency color value from the file header. For gif images
   transparency on the static background works even if KeyColor=-1.
/BANNER   - returns control to installer immediatelly after plug-in
   activation. Not depends on installer page - parent window NULL.
/NOCANCEL - disables 'exit on user click' default behaviour.
/PASSIVE  - not forces splash window to foreground.
FileName  - splash image filename (with extension!). Bmp, gif and jpg
   image types are supported.

For example:

     launchersplash::show TTOTAL_CMD 200 3000 0 0 -2 "$PLUGINSDIR\catch.gif"
or
     launchersplash::show /NOUNLOAD TTOTAL_CMD 0 1000 600 400 0xFF6410 /BANNER "$TEMP\spltmp.bmp"

    Use /NOUNLOAD with /BANNER key - this case plug-in not waits for
    the end of 'show' and returns control to installer. If used in .onInit
    function, /BANNER key requires 'ShowWindow $HWNDPARENT 2' in .onGUIInit


2)   launchersplash::wait

     Waits for the end of performance :). If 'show' already finished -
     exits immediately


3)   launchersplash::stop

     Terminates banner.


4)   launchersplash::play /NOUNLOAD [/LOOP] FileName

FileName - sound filename to play (with extension, wav, mp3 ...).
Empty Filename string "" stops sound.
For example:

     newadvsplash::play /NOUNLOAD /LOOP "$PLUGINSDIR\snd.mp3"
     newadvsplash::show 2000 1000 500 -1 "$PLUGINSDIR\iamfat.jpg"


4)   launchersplash::hwnd /NOUNLOAD

Gets splash window handle.
For example:

     launchersplash::hwnd /NOUNLOAD
     Pop $0 ; $0 is window handle now

Compatibility:
Basic - Win95 and later.
Fadein/fadeout - win2k/winxp.
