int PEXInvertMatrix( PEXMatrix transform, PEXMatrix transform_return )
Zero if successful; non-zero if unsuccessful.
Invoke PEXInvertMatrix to compute the inverse of a transformation matrix.
If the matrix is non-invertible, then this function returns a status of unsuccessful.
The two arguments may be the same variable, in which case the inversion is performed in-place, overwriting the original transform.
None.
