Ok, understood - having both besides each other sounds sensible. Having
the ability to block certain actions makes this approach even more
powerful.

Yes, you are right to a certain degree - the root problem here is that
moveWindow is used for both window animations and viewport changes, what
makes it hard to distinguish both.

Interesting question ;-)
I thought of only drawing it at another place (with the
xTranslate/yTranslate members), but in this case, no screen interaction
would be possible.
