WebMatrix types can be identified by tracking the OpenGL commands used to create them. This can be simple if glTranslate, glScale, and glRotate commands are used. If glLoadMatrix or glMultMatrix are used, it's still possible to rapidly check the loaded matrix to see if it matches one of the common types.
