The other option is to use the gl in a draw callback to modify the gl
texture matrix.

Use glMatrixMode(GL_TEXTURE) to get the texture matrix stack and use the
usual gl matrix and other types of transformation.

Be sure and set the matrix mode back to GL_MODELVIEW or whatever state you
read on the way in.
