Expand description
Rotate a transformation by premultiplying.
The premultiplied matrix is of the form [ cos(deg) sin(deg) -sin(deg) cos(deg) 0 0 ].
m: Pointer to matrix to premultiply.
degrees: Degrees of counter clockwise rotation. Values less than zero and greater than 360 are handled as expected.
Returns m (updated).
