Review request for kwin and Martin Gräßlin.

Description
-------

That one has cost me nerves.
What happens is that kwin gets locked trapped in it's strut handling because it \
already is in an invalid area, also the wrong clipping area was used. As a solution i \
                check
- are we locked?
- are we changing the screen
--> put window into bounds of the new screens workarea

The patch applies to 4.8, so ideally Kai can test & use it, but i'd rather apply it \
to master only - it might cause unforeseen regressions...

This addresses bug 274466.

Testing
-------

Could reprouce test from bug, now the window moves below the titlebar and from there \
just on.

Thanks,

Thomas Lübking
