Feature request: Allow resizing the touch region

[ericshu6]

I have a rather big iPad, and I'm trying to play osu! with this software. It works great, except that the screen is too big and there's so much distance for the pen to travel across the screen. I wish that we could resize the "virtual tablet" so this would not be an issue.

Edit: My iPad doesn't support Stage Manager, so I can't resize the browser window.
