debug: Add GTK_DEBUG=snapshot
This causes the snapshotting algorithm to dump all widget nodes into their own container node. We then name that group accordingly (ie "GtkSwitch<0xdeadbeef>") so you can easily see which node belongs where. The feature is toggleable in the inspector's visual tab. There's a few problems with it, becuse GtkSnapshot optimized container nodes away if they are not needed, so we are losing some widgets...
