Map the surface as a fullscreen surface. On the output the
surface is assigned to. Leaving it to NULL will allow the compositor
to choose one output. The client can use different fulllscreen
method to fix the size mismatch issue: default, scale, driver
and fill.
Hints to indicate compositor how to deal with this fullscreen surface.
"default" means the client has no preference on fullscreen
behavior, policies are determined by compositor.
"scale" means the client prefers scaling by the compositor.
Scaling would always preserve surface's aspect ratio.
And the surface is centered.
"driver" means the client wants to switch video mode to the
smallest mode that can fit the client buffer. If the
sizes do not match, black borders are added. And the
framerate parameter is used for "driver" method,
to indicate the preferred framerate. framerate=0 means
that the app does not care about framerate
"fill" means the client wants to add blackborders to the
surface. This would be preferring 1:1 pixel mapping
in the monitor native video mode. The surface is
centered.

- Map the surface as a fullscreen surface. There are a number
- of options here: on which output? if the surface size doesn't
- match the output size, do we scale, change resolution, or add
- black borders? is that something the client controls? what
- about transient surfaces, do they float on top of the
- fullscreen? what if there's already a fullscreen surface on
- the output, maybe you can only go fullscreen if you're active?
