olution would be that we
introduce a repaint_window event to wl_output interface,
so that camera/video applications can synchronize themselves with this event
instead of surface frame events.
Compositor can send a timestamp and duration of repaint window to the clients.

If view is set to be entirely transparent,
there is no need to accumulate its damage.
This is an important optimization for
using view transparency. Because otherwise
transparent views are rendered like an
opaque view, and their pixel values
are set to 0 in fragment shader.
