The id pool used for the actor's id should be a per-stage field. At some point, we might have a Stage mapped to multiple framebuffers, or each Stage mapped to a different framebuffer; also, on backend with low color precision we don't want to exhaust the size of the available ids with a global pool. Finally, it's yet another thing we can remove from the global Clutter context. Having the id pool allocated per-stage, and the pick id assigned on Actor:mapped will make the whole pick-id more reliable and future proof. http://bugzilla.clutter-project.org/show_bug.cgi?id=2633 https://bugzilla.gnome.org/show_bug.cgi?id=647876
