// TODO :
// - CORE STUFF
// o put all the sector/wall geometry in VBOs
// o optimize the update[sector|wall] functions to diff the changes
// o make occlusion queries every n frames (cvar)
// o there's still a texture alignment problem with slopes (waterfall in launch facility)
// 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)
