output_damage_whole_container: damage subsurfaces

Browse source 
This adds an iterative call in `output_damage_whole_container` to
damage the subsurfaces for all visible views that are inside of the
container. This is needed to damage subsurfaces that extend outside the
box of the container. Without this, those subsurfaces will create
artifacts when moving or resizing.
