According to what aseigo was telling me this shouldn't really be the case.  
In-window drawing is supposed to be very fast, including blending.  But this 
seems not not necessarily be the case -- or maybe it's fast for smaller 
blending jobs.  Also, it seems to handle blending quite well once it's at its 
final transparency, so maybe cutting to that and then painting on 
graphicitems would work (if that flashing can be done away with).

This is another possibility.
