There are both some good changes and some terribly hacky changes in this commit. - Server uses a different struct than client now for windows, so arbitrary compositor things like effect parameters can be added without having to rebuild everything. That's good. - Client window structs no longer attempt to track or use window locations. That's good. - Windows do not destroy in response to the destory command, but rather, a special animation is triggered; the end state for this animation calls the actually window destruction code. That's a hack. - Animations are based on rendered frames, not on time. That's a hack.
