[PATCH weston 1/2] clients: Allow simple-egl to use wl_surface_damage_buffer

[Derek Foreman]

wl_surface_damage_buffer landed ages ago, but in order for GL to
use it the client must bind a wl_compositor version >= 4 (the
version where damage_buffer was introduced).

This patch updates the bind version and allows
eglSwapBuffersWithDamage to actually use the provided damage
rectangles instead of performing full surface damage.

This log is much longer than the patch.
