ImGUI menu docked resolution (Switch)

[Ammako]

In handheld, the menu renders at 720p, makes sense.

But when docked, the menu renders at 1080p, regardless of what resolution you're actually docking at. I do 720p docked, so the menu downscales from 1080p to 720p and looks pretty bad.

Handheld

Docked

It's maybe not that big of an issue right now since the menu is unusable when docked anyway, but it would be a good idea to make it so the menu matches the output resolution for when the menu may eventually be useable with a controller one day. If it's not possible to detect docked output resolution, then some option to manually set a resolution for the menu would be helpful.

It also affects the appearance of the autosave text, and the "Press - to access enhancements menu" that shows up at the start, so autosave ends up looking blurry when docked.

Actually: it's nice to have randomizer tracker stuff up while playing, and that ends up squished and hard to read too. So it's a bit more of an issue than I first thought.
