Please consider that when the user drags, I don't have to save cpu
cycles - at this moment, the user doesn't expect the drag operation
to finish as fast as possible, it only has to finish at the moment
he decides to.  Meanwhile he will gladly give me 95% of his cpu.
(and dragged pixmaps need much less cpu)
