Robert Bragg dae569b468 [debug] Adds a dump-pick-buffers CLUTTER_DEBUG option
Now if you export CLUTTER_DEBUG=dump-pick-buffers clutter will write out a
png, e.g.  pick-buffer-00000.png, each time _clutter_to_pick() is called.
It's a rather crude way to debug the picking (realtime visualization in a
second stage would probably be nicer) but it we've used this approach
successfully numerous times when debugging Clutter picking issues so it
makes sense to have a debug option for it.
