You can to this in your draw callback:

     1. Enable texture with pfEnable(PFEN_TEXTURE)

     2. Apply a pfTexEnv with pfTexEnv::apply

     3. Apply a pfTexture with pfTexture::apply

     4. Draw your OpenGL geometry

Or you could use a pfGeoState that encapsulates all those 3 and apply it
in your draw callback just before drawing your OpenGl geometry.
