This passes 33/37 deqp tests related to partial_update, 4 are not
supported. Tests not supported:
dEQP-EGL.functional.negative_partial_update.not_postable_surface
dEQP-EGL.functional.negative_partial_update.not_current_surface
dEQP-EGL.functional.negative_partial_update.buffer_preserved
dEQP-EGL.functional.negative_partial_update.not_current_surface2
Reason: No matching egl config found.
v2: Remove unnecessary return statement. Keep function names
consistent. (Emil Velikov)
Add not supported list to commit message. (Eric Engestrom)
v3: Remove explicit with_damage variable and swap_buffers_common
function. Make SwapBuffers and SwapBuffersWithDamage(NULL,0)
equivalent in behavior. Fix called via comment for
swap_buffers_with_damage. (Eric Engestrom)
Rework try_buffer_damage into set_damage_region as it is being
called only from set_damage_region.
v4: Undo the rework done in v3. Fix code indentation (Emil Velikov)
