The JPEGs look terrible

[endrift]

After flashing my SV04 with your Marlin fork and this touchscreen repo, well, it looks really bad. I've noticed that other DGUS-based repos use BMP, and I'm not sure if you can use PNG so it's smaller than BMP, but these overly compressed JPEGs make it look just awful and I'm really tempted to just redo all of your graphics for you if you can't make not-terrible-looking versions.
