Hi, Sami Jaktholm :)

I've tested your branch now and this looks like another big improvement to me.
Everything works exactly like you described. Top job !

I also think that the solution you found is our best bet at the moment and it
will still affect just corner- and center-gridded windows to restore to original
size when dragged inside expo.

This solution is just slightly inconsistent, compared to the behaviour of grid-
semi-maximized and maximized windows, which will keep their size when dragged to
a new viewport - but it is 100 times better than the version we have in trunk now,
which also acts inconsistent and makes gridded windows jump around and follow the
user's moves in expo...

Restoring the window to original size is always the best solution, because gridding
it back requires just one shortcut, while it can be nerving to have to manually resize
to get back to original size.
Btw, there is still a working workaround for users, who want to move a corner- or center-
gridded window from one workspace to another (rotate to cube face with window) - this
one works perfectly for gridded windows as well...

I still have to apply your other improvements here, and still have to find a solution
for snapping off horizontally maximized windows correctly and easily...
