Adding an option for maintaining window aspect ratio in the graphics menu

[Ubry004]

Hello, I'm working on adding a "maintain aspect ratio" option to the graphics menu. I'm opening this issue since I'm doing this for an assignment and they need an issue link for it. Thanks.

This sounds an interesting thing they make you do for an assignment, good luck with that, if you need any help with the codebase feel free to ask in the discord
