Fullscreen *or* resolution scaling.

My monitor is very high resolution. I do not want to play this game at my monitor's maximum resolution; I don't need that level of visual fidelity and it makes my older GPU sad.

Unfortunately, since there is no fullscreen option and there's no resolution scaling, what I've actually had to do is run the game in a teeny-tiny window and the steam Lossless Scaling app. Which is fine I guess but it doesn't work over Moonlight/Sunshine, so that's annoying.

Please add some way to drive this game that (1) takes up the entire screen and (2) is at a lower resolution than my monitor.
