Thanks again to Alondria for adding: math support for
rot * rot, vec / rot, == and != overriders for Rotations and Vectors. Also: llRotBetween(), llGetRegionTimeDilation(). And fixing: Error in LSL2CSConverter that botched a variable with a type name in it (ex: rotationCenter) Fixed: Error in LSL2CSConverter that parsed which() loops incorrectly. Fixed: Changed definition of Quaternion to <x, y, z, r> from <x, y, z, t> (As per LSL) Finished: llEuler2Rot()afrisby
