Hi,
I just tried it out at now it is definetly faster. It is fast enough to be
usable. The dragging is still a bit slow but that matter of seconds not
minutes as before. Would it be possible to have a scrollable visualization
instead of a draggable one?
+1 :)
Thanks really really a lot Alex.
Cheers,
Fabrizio

Stupid problem it was. The ROView object keeps a
list of elements that
are visible within the window. In the drawing loop, the view
iterates over
each elements and check if the element is visible before drawing it.
However this is completely unnecessary.
why? because when you explain it it looks something smart to do :)
But there are still some optimizations to be done
