This work precalculates a 24bpp colormap (in I_SetPalette) in order to use 24bpp RGB values for lighting instead of the palette mapping table from the COLORMAP lump.
Converted to 24bpp display with computed colormap of darkened RGB col…
…ors per light level.
Increased NUMCOLORMAPS from 32 to 64.
Fixed wipe effect but now it is per 1 column instead of per 2.
Fixed fuzz effect closer to original and fixed inverse colormap.
Fixed inverse colormap.
Fix compilation via scons
SConscript.core was missing jpeg_memory_src.cpp.
