ui.box: refactor layout_update
Current layout_update doesn't consider max hint priority. for example, if it
has hint_max, the size is hint_max value regardless of weight or fill.
moreover, if it has hint_aspect with hint_max, hint_min can be ignored.
(test that aspect(1,3) max(50,150), min(70, 70) then, size has (50, 150))
It seems that hint_max is considered as high priority. however, if hint_min
greater than hint_max, hint_max is ignored.
In order to resolve the hint priority conflict, this refactoring supports
following hint priority.
- HintMin + HintAspect
- HintWeight, HintFill
