Author: Brian Paul <[email protected]> Date: Tue Apr 7 08:33:43 2009 -0600 mesa: only clear matrix MAT_DIRTY_INVERSE flag when we actually compute the inverse If _math_matrix_analyse() got called before we allocated the inverse matrix array we could lose the flag indicating that we needed to compute the inverse. This could happen with certain vertex shader cases.
