We might pick an actor that needs relayout. I've seen this happen inside hiding / unmapping in particular. In this case, calculate_clear_area () will call clutter_actor_get_abs_allocation_vertices () which in turn will force a relayout. However, this is not what we want, because: 1. We don't want to run layout during picking. 2. If the actor needs an allocation, then the pick stack could not have used an up-to-date allocation, because it is not computed. Therefore this clear area would use a potentially completely different allocation than the one stored in the pick stack. Thankfully, clear area seems to be used as a cache/optimization, so let's just avoid computing it if the actor is not allocated.
