Jan Holesovsky 5ca1936975 rendercontext: Mass fix of using the wrong size. 
In the paints, we must use the size of the Window for the computations, not of
the RenderContext - the RenderContext can be much bigger than the Window in
the double-buffering case.

Fixes for example the list boxes, and many others.
