  This is a great resource.
  http://www.andersriggelsen.dk/glblendfunc.php
  
  We support the following blend modes
  
  Translucent(7) checked off
  glBlendFunc(GL_ONE_MINUS_DST_COLOR, GL_ONE);
  
  Blended(9) checked off
  glBlendFunc(GL_DST_COLOR, GL_ONE);
  
  And in IWD
  Translucent(7) and Blended(9)
  glBlendFunc(GL_SRC_COLOR, GL_ONE);

  Thank you very much! That was exactly what I was looking for
  
  I figured out how to duplicate these blending effects using ImageMagick:
  
  Translucent(7)
  glBlendFunc(GL_ONE_MINUS_DST_COLOR, GL_ONE);

  convert.exe source.ext dest.ext -channel rgba -fx "(u*(1-v))+(v*1)" result.ext

  Blended(9)
  glBlendFunc(GL_DST_COLOR, GL_ONE);

  convert.exe source.ext dest.ext -channel rgba -fx "(u*v)+(v*1)" result.ext

  Translucent(7) and Blended(9)
  glBlendFunc(GL_SRC_COLOR, GL_ONE);

  convert.exe source.ext dest.ext -channel rgba -fx "(u*u)+(v*1)" result.ext

  @ScottBrooks
  
  I have just 2 more related questions, if you would be so kind:
  
  1) It seems the BAM frame size limit of 255x255 px (or perhaps 256x256 px) has been lifted in the EEs. Can you confirm this?
  2) In which scenarios does the second entry in the BAM's Palette take on the special properties of being the "shadow" color, or does it always?
  
  Thank you very much for your time!

  1: 256x256 has been lifted(ish). If it's compressed the engine still needs to decompress that bam to render it, so going over that should still be avoided. If it's a bamv2, then we can send that data directly to the card, so it renders much faster(but then you skip the fancy effects you can do to a bam)
  
  2: When the bam is rendering, it asks the palette system how many entries are reserved. If the 2nd entry matches the shadow color of 0x00000000, then it returns 2 Otherwise it returns 1. So basically if the 2nd entry is the shadow color, then it will treat it as such. Otherwise it just uses the 1 reserved entry of the color key green.

  I did some playing around with the new alpha bit by patching palette entries in WeiDU. You can do some never-seen-before stuff such as this smoke effect.
