...and unify region overlay and snap-to-edge overlay into overlay.c. Snap-to-edge overlay is delayed for 500ms to prevent flickering when the view is dragged from an output to another (demo in discussion labwc#1613). This also fixes a bug that region overlay is not shown when a modifier key is re-pressed.
