This seems like it could be worth the (potentially substantial) extra
work.  I think it would be a useful feature.  If the new GAL library is
deemed a worthy future path of travel, then I wonder if the XOR
technique currently used for object dragging operations would go away. 
And we would simply use a redraw technique, but my assumption could be
wrong.  And I have wondered about how we could do the interactive
rubber-banding box drawing without XOR, same way Torsten?

Again, I do think the feature you Lorenzo highlight would be slick, and
would actually be a little more intentional than some of the artifacts
we have now.  Those current artifacts are more like litter left behind
after a picnic :), but seem to have been found useful.

I too still have computers that eventually stopped working well for me
as software advanced.  And my 8 month old android capable cell phone is
already obsolete...  but somehow I don't think any of the guys writing
software for it really care, since their time is valuable.
