So what should be the desired behaviour? Simply delete all the objects
in the layer that you are deleting? Or move them to the active layer?
Every view needs to have an active layer, so what should Ipe do when you
delete a layer that's active somewhere? I think it would be a rather
unpleasant surprise if Ipe simply switched the view to a different
Of course would we could do is enable "delete" in the side menu for all
layers, and then show an error message if it is active in some view, to
