// here lies the GREAT JUSTICE RENDERER
// TODO :
// - CORE STUFF
// o put all the sector/wall geometry in VBOs
// o use BufferData only once for VBOs
// o there's also the texture alignment problem Hunter reported (san andreas fault)
// o also sliding doors are still fucked up sometimes (like under the bar in E1L2)
// o port glowmaps and detail maps from hacked polymost (:(
// o shading needs a lot of work
// o remove all the IM matrix crap and write real functions now that it works
// o polymer.c possibly needs to be split in several source files
// o some crap really needs factorization
// o ... possibly more important stuff I don't have in mind right now
// - SPRITES
// o port sprite panning and fullbrights from hacked polymost (:(
// - SKIES
// o figure a better way to handle ART skies - maybe add symetric caps that would fade to black like a big gem or something wow this is a long column lol ;0)
// o implement polymost skyboxes
// - MDSPRITES
// o need to reimplement them - hopefully the loader can be reused without too much hassle
// o need to truly convert MD2s to MD3s with proper scale offset to just dump the data into VRAM
// o need full translation and rotation support from CON to attach to game world or tags
// o need to put frames into VBOs and blend between them
