Change the damage extension reporter to queue up events after we chain
to the wrapped functions. Damage events are typically sent out after
the rendering happens anyway, since we submit batch buffers from the
flush callback chain and then flush client io buffers. Compositing
managers relie on this order, and there is no way we could reliably
provide damage events to clients before the rendering happens anyway.
By queueing up the damage events before the rendering happens, there's
a risk that the client io buffer may overflow and send the damage
events to the client before the driver has even seen the rendering
request. Reporting damage events after the rendering fixes this
corner case and better corresponds with how we expect this to work.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
