Just a small bit.  In X11 a lot of windows are created (every button, 
menu, etc. are separate windows), and X11 is fast when it comes to 
window creation.  And in any case, we would have to apply the frame 
parameters again (font, color and such) and that still takes some time. 
 They could also be cached of course so we only re-apply what has been 
changed, but then I think it is more effort than it is worth.
