This prevents windows from being opened directly on top of eachother, and provides default behavior for when window position is not specified. The new behavior is as follows: - Windows that have been created without a set position are assigned one by WindowServer. - The assigned position is either offset from the last window that is still in an assigned position, or a default position if no such window is available.
