Fix game screen scaling for 21:9 screens

[Srpboyz]

The menu ui is fine, but the game screen for 21:9 resolutions increases the height too much. This get annoying when jumping as the camera follows the character vertically

21:9

16:9 for comparison

The camera zooms in when the aspect ratio is not 16:9 to avoid giving players with higher aspect ratios an advantage (seeing more left/right). Not sure how I could "fix" this in a fair way.

black borders could appear for higher ratios keeping the game still 16:9
