Higher resolution images

[TheBeruriahIncident]

Right now we downscale any larger image to 1200x1200. We may want to support higher, especially as phones are now faster. On initial testing, all the algorithms seem fine with 4000x4000 on 2020 SEs, although saving images to Google Drive seems surprisingly slow.

We'd need to decide whether to have set resolutions per device model, have several configurable options, or have a textfield configuration.

Note that the X for scales and leaf icon are too small with high res, so we'd have to scale those.
