  21. Actually, an undocumented bonus feature of QuickTime 1.5 is that when it is
  22. installed QuickDraw does do dithering from 32-bit/pixel sources to
  23. 16-bit/pixel destinations. QuickTime 1.5 also does this dithering itself
  24. when decompressing still images (or movies played in high accuracy mode) to
  25. 16-bit destinations.
  26.  
  27. Just another reason to update to QuickTime 1.5...
