The problem with that is you'd end up reshading the whole scene on each 
python-initiated redraw, which would be a waste of CPU time if you 
weren't doing anything to the scene.  Also, building shading lists 
should only be done in shaded drawing mode (and up).

As an example, if you were doing some 2D overlay thing (like for note 
taking or whatever) you wouldn't want to be spending drawing time 
reshading when you didn't have to.
