[PATCH weston 00/11] implement damage_buffer

[Derek Foreman]

As usual I've included random NOPwork in the vicinity of the
important changes.

It was convenient to have a way to transform a region with a matrix
so I cherry-picked Jason Ekstrand's patch to do so out of my transform
series from over a year ago.  This changes pixman zooming, which is
utterly broken now and works properly (if slowly) after the patch.
If that's a problem I can keep the function and stop using it in
the pixman renderer, I just didn't want to change the patch.

There should be no problem with interaction between damage and
damage_buffer.  damage_buffer just converts its damage into
surface co-ordinates at commit time.  The implementation came
out fairly clean so I removed warnings about mixing the two
from the wayland proto xml.

I didn't bother making toytoolkit prefer damage_buffer if
available (though I did a hack job of it for testing
weston-subsurfaces, not included here).  simple-damage has
been updated with a --use-damage-buffer switch for testing.

There's a bit of a bug fix in here too - currently if we post
damage with negative width or height those values are passed
right on to pixman which whines in the log.

Thanks for looking,
Derek
