StThemeNodes may have properties - namely shadows - which paint outside an actor's allocation. This is not a problem unless drawing is redirected to an offscreen buffer, in which case the actually painted size is needed in advance when setting up the buffer. Add a convenience method to calculate an allocation large enough to paint the node. https://bugzilla.gnome.org/show_bug.cgi?id=619025
