If the surface switch involved a resize, we were doing the redraw at the old size rather than the new, because the update of screen.width and screen.height was being done after the setFrame method calls which triggered a redraw. Normally this isn't very noticeable because typically after the guest triggers the window resize it also draws something to it, which will in turn cause us to redraw. However, the combination of a guest which never draws to the display and a command line setting of a screen size larger than the default can reveal odd effects. Move most of the handling of resizes to the top of the method, and guard it with a check that the surface size actually changed, to avoid unnecessary operations (including some user visible ones like "recenter the window on the screen") if the surface is the same size as the old one.
