WindowServer now tracks whether windows are occluded (meaning that they are completely covered by one or more opaque windows sitting above them.) This state is communicated to the windows via WindowStateChanged messages, which then allow GWindow to mark its backing store volatile. This reduces the effective memory impact of windows that are not at all visible to the user. Very cool. :^)
