[#641] fixed `fill-max` and `flex-xxxx` scaling mode not obeying the max defined scaling size

realized that when working on my game, as the `me.video.setMaxSize()`
was not doing anything.

Also noticed an exception being raised or some further black screen
issue when scaling way beyond the level size, i'm tracking them down
now.
