It occurred to me that even if the pixmap itself exceeds this limit, we 
obviously never draw it entirely, it's always clipped to the refreshed bit 
(even though this is probably not properly enforced in the current code). In 
any case, it's certainly at least possible to bitBlt the relevant part of the 
preview pixmap to another pixmap and draw that, even if directly drawing only 
the relevant bit doesn't work.
