1.0.3 - WIndows - Battle UI is downscaled by one increment of 16:9 ratio even when the game window ratio is already 16:9

some observations while calculating the battle UI offsets.

It looks like the battle UI is scaled down to the next lowest16:9 ratio regardless if it would fit the existing game window size

the default game window of 1280x720 is already a 16:9 aspect ratio, so no downscaling is needed
however, the game downscaled to the next lowest 16:9 ratio increment.
which results in small black bars around the battle UI.
