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.
