apply the OpenGL state attributes.
The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.
Reimplemented from osg::StateAttribute.

Set the tex gen planes from specified matrix.
Typical usage would be to pass in a projection matrix to set up projective texturing.
