Chris when you call setLODRange it creates a pfTexLOD which the
pfTexture holds a pointer to so it can apply it in in the
pfTexture::apply(). pfTexLOD is a display listable libpr command. The
setLODRange() method looks like it is safe for the CULL process.
To change the pfTexLOD multiple times per frame you should not call
setLODRange() you should create multiple pfTexLOD's and add them to your
pfDispList before each addition/reference of the desired pfTexture. The
pfTexture::apply() will use the current pfTexLOD if you have not created
one with pfTexture::setLODRange().
