layout: Add the ability to deactivate fullscreen surfaces

Deactivating fullscreen is a special case so we need to handle it
similarly to dialog/popups.

This adds an additional schedule for repaint in the fullscreen part to
force a redraw, otherwise deactivation/activation would need to inflict
any sort of damage to trigger a redraw.
