// here lies the GREAT JUSTICE RENDERER
// TODO :
// - recursive drawrooms with cliplane stack (support for full portal engine with occlusion queries)
// - crossed walls (tier drops stones)
// - skies
// - mirrors
// - fullbright (multitexture OR)
// - masks and sprites ! (use sortcnt and regular drawmask or recode it ?)
// - classic shading
// --------------------- CLASSIC LIMIT ---------------------
// - mdsprites (tags)
// - lights (dynamic phong)
// - dynamic shadowmaps
// - normalmap palette (unified gpu program, parallax mapping)
// - shadow volumes
// - hardware particles
// - multitextured decals ? (on models too)
// --------------- FIRST PUBLIC RELEASE LIMIT --------------
// - horizon mapping (precalculate the horizon maps and store them into the gl cache ?)
// - post processing ([HDR-]bloom and possibly DOF)
// - MD5 (hardware skinning ?)
