(svn r2736) -Codechange: De-mystified GfxDrawFillRect a bit, and used enums from table/sprites.h. You can now change the number of bits used for sprites and switches in the SpriteSetup enum and the rest should work automagically. Can be used to increase the number of active sprites to 2^19 in case there are no colortables (recolor sprites) in any newgrf. We should possibly move the the colortables to an own list, but how to detect them in a newgrf.
