Fix CFX_Matrix.RotateAt()

The translations were in the opposite order they should be.
First the specified (x, y) coord needs to be translated to the
origin, then rotation should be applied, then the translation should
be reversed. To translate (x, y) to the origin, the initial
translation should be Tx = -x, Ty = -y.
