mostly taken from https://codeberg.org/srb2classic/srb2classic/pulls/156 manually done to ensure we only port things that are guaranteed to not cause any potential desynchs we should probably run this ourselves sometimes aswell

inverse order so the 20-80 becomes 80-20 translucency, no need

for other tables (thus 1090,2080,5050,8020,9010, and fire special)

\todo render all this obsolete by writing some goddamn realtime

translucency and 32-bit color support
