WindowServer will now send out a WindowStateChanged message to clients when one of their windows is minimized. This is then forwarded to the GWindow, which will try to mark its underlying window backing store as volatile. This allows the kernel to steal the memory used by minimized windows in case it starts running low. Very cool! :^)
