MetaWindowActor: fix updates with multiple size changes in one frame

Browse Source 
We must set x11_size_changed even if we are frozen, as every window
size change makes the X server drop the pixmap, and we might lose
the information at the next thaw() if the window changes size
twice in one frame (so we would keep drawing with the old pixmap
until something else causes another resize)
