Functions
MercuryPoint	Rotate2DPoint (float fAngle, MercuryPoint pIn)
	Rotate (in 2D) the X and Y components of a MercuryPoint.
void	AngleMatrix (const MercuryPoint &angles, MercuryMatrix &matrix)
	Produce a matrix out of a rotation x, then y then z (how Mercury does it).
void	R_ConcatTransforms3 (MercuryMatrix in1, MercuryMatrix in2, MercuryMatrix &out)
	Concatenate matrices, not using the last row. (faster when applicable, and breaks things that don't expect that last row.).
void	VectorRotate (const MercuryPoint &in1, const MercuryMatrix &in2, MercuryPoint &out)
void	VectorIRotate (const MercuryPoint &in1, MercuryMatrix &in2, MercuryPoint &out)
	Legacy vector rotation only functions. It's similar to vector-matrix multiplication.
