Surfaces are created by the client.
Clients don't know the global position of their surfaces, and
cannot access other clients surfaces.
A surface manages a rectangular grid of pixels that clients create
for displaying their content to the screen. Clients don't know
the global position of their surfaces, and cannot access other
clients' surfaces.

buffer back to the client.
