I
​ checked up the thesaurus and the closest contender was "size", so I guess
you already have the best name :)

​Should this simply be called "get"? Since the above request is "destroy",
and the one to set the scale and crop state is called "set".

​I have trouble understanding this paragraph. Perhaps cutting everything
before "In other words" will make it clearer? Or maybe its just my
inexperience with Wayland.
