Robert Bragg c1aac36d35 wayland-surface: Adds queue-damage-redraw signal
This adds a signal that's emitted whenever a wayland surface is damaged
that allows sub-classes to override the default handler to change
how clipped redraws are queued if the sub-class doesn't simply draw
a rectangle. The signal can also be used just to track damage.
