protocol: mention wl_surface events from wl_output.{scale,transform}

Browse source 
The wl_output events should not be used anymore for guessing the
preferred scale and transform of a surface. We have explicit events
for that now.

The geometry event will be followed by a done event (starting from

Clients should use wl_surface.preferred_buffer_transform instead of the
transform advertised by this event to find the preferred buffer
transform to use for a surface.

It is intended that scaling aware clients track the
current output of a surface, and if it is on a scaled
output it should use wl_surface.set_buffer_scale with
the scale of the output. That way the compositor can
avoid scaling the surface, and the client can supply
a higher detail image.
