// - crossed walls (tier drops stones)
// - skies
// - mirrors
// - fullbright (multitexture OR)
// - masks and sprites ! (use sortcnt and regular drawmask or recode it ?)

// --------------- 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 ?)
