UI Elements = menus and dialog boxes.

GtkRadiant currently does a re-render of the entire scene when the window is 
exposed (and ignores expose events from menus and dialogs because that would 
make them very unresponsive). Perhaps this scene re-render should only happen 
when the scene changes rather than every time the window is exposed. I assume 
other apps keep a copy of the framebuffer for each window and redraw that after 
being exposed. 
I suspect the current behaviour is a hack, perhaps related to a problem getting 
it to work right with GTK win32. If it's the same on win32 GIMP then it 
suggests a GTK issue.
