This will be used by the next commit to determine when a window geometry change should be ignored or not. Normally, it would be enough to just check if the position and sizes changed. The position, in this case, is relative to the client buffer, not the global position. But because it is not global, there is one, admitedly unlikely, situation where the window state is updated while the client size and relative positions don't change. One can trigger this by e.g. tiling the window to the half-left of the monitor, then immediately tile it to half-right. In this case, the window didn't change, just it's state, but nonetheless we need to notify the compositor and run the full move/resize routines. When that case happens, though, the MetaWindowWayland is tracking the pending state change or a move. And this is what we need to expose. https://bugzilla.gnome.org/show_bug.cgi?id=780292 Issue: #78
