Hey, I've been trying to remember something about the way CA and the windowserver interact for a few weeks but I can't find anything about it. I remember somewhere there was a setting for maybe the backing layer of how a window was set up? And there were a few hidden ones? i remember that one of these settings was how minimized windows were implemented because the layer was set up to copy some other layer, and then shrunken, so that way you get minimized windows changing when the window changes for free.
