Legend:
INTERNAL RESOURCE - function contain hardcoded path to resource that engine required (optional in most cases)
OBSOLETE, UNUSED - this function no longer used and leaved here for keep binary compatibility
TODO - some functionality not impemented but planned
FIXME - code doesn't working properly in some rare cases
HACKHACK - unexpected behavior on some input params (or something like)
BUGBUG - code doesn't working properly in most cases!
TESTTEST - this code may be unstable and needs to be more tested
g-cont: - notes from engine author
XASH SPECIFIC - sort of hack that works only in Xash3D not in GoldSrc
