rubber redraw problem example

Marcel, Luka,

Look the screenshot witch reproduce the problem. It easy to do : open a large
picture, zoom to 300, and start to select an area. Now move the selection very
quickcly outside the current visible canvas area. The scrollview will move the
content automaticly, but sometime, the rubber is not cleanned, accordinly with
the mouse mouvements. 

I suspect a problem about to dispatch messages to force the rubber to be
cleaned. Note the rubber is draw/cleaned using the same method drawRubber()
witch use a NOT raster operator.
