/* For libdecor we _have_ to dispatch immediately, because libdecor state
* strongly depends on the "current" state of the window. For example, if an
* application calls SetWindowSize right after this, libdecor will still
* think the window is fullscreen and not floating because configuration has
* not yet occurred, so the call will get completely ignored! So, take the
* time penalty and ensure that libdecor state matches SDL state.
*
* TODO: If Wayland_SetWindowSize ever stops checking for floating state,
* this can be removed.
