 * @META_LATER_CHECK_FULLSCREEN: used by Mutter to see if there's a fullscreen window
 * @META_LATER_SYNC_STACK: used by Mutter to send it's idea of the stacking order to the server
 * @META_LATER_BEFORE_REDRAW: call before the stage is redrawn
 * @META_LATER_IDLE: call at a very low priority (can be blocked
