Review request for Plasma.


Summary
-------

This patch fixes the bug 176280 where resizing a horizontal panel to be larger would break the desktop.  It applies to kdebase/workspace/plasma/shells/desktop/panelview.cpp.  What appears to be the problem is at times panels will begin to bleed over into positive coordinates (they are meant to be in negative coordinates).  A function is added to check for this overflow and fixes it by setting the y position to be -(height_of_panel + 10).  This is a collaboration of a few people and is basically just a hack that has worked on 3 separate machines.  It should help to have more knowledgeable eyes check over it and maybe provide a better way of solving the problem.  Thanks for your time.
