The slow zone redrawing during zoom is a problem per se. Even with the old 
zoom factor, the zone redraw slowed down the zooming (although not to a point 
where it becomes unusable).

Maybe the problem should be attacked from that angle: Reduce the redrawing 
during zoom, i.e. don't do a complete redraw for every zoom step. There is 
not really a point in continuing the drawing while the user has already given 
another zoom command...

I haven't checked if/how this could be implemented, but maybe it isn't that
