boxpointer: If available, use source actor for constraining
If a source actor is set, use that for determining the arrow side (i.e. whether the BoxPointer widget should expand in a certain direction). This is better because it ensures that the popup is displayed on the same monitor as the widget it originates from. Without this, entering text with a vertically aligned input method close to the bottom of a monitor would expand the BoxPointer downwards on the monitor beneath it, instead of upwards, which is what one would expect. https://bugzilla.gnome.org/show_bug.cgi?id=786886
