    Oh exactly.  They'd just get one frame of animation out of the whole 
thing!  We can probably find a way to feed that back up the chain to let 
the renderer know "Hey, I skipped 24 out of 25 frames of that 
animation... you should probably fall back to QPainter" or something. 

    I'll have a go at this over the weekend.  Your OpenGL code doesn't 
look too bad to me though.  :)
