Subject: Patch #1121337 (CGA rendering in early LEC titles). Differences
 against patch:   o Updated documentation   o Fixed text colors   o
 Implemented Hercules dithering

Ditherers are based on loom ega and monkey ega, so for zak and mm they're
wrong, i.e. these games look better than with original ditherers.

TODO:
  Proper ditherers for zak & MM
  EGA ditherers for VGA SCUMM v5 games
