I Upgraded to LVGL 9 and it Went Terribly

Lots of you have been asking me to upgrade my gauge designs to use LVGL 9 so we can test Scales instead of Meters. Well, I tried, but it went terribly, and there's so much wrong!

I still love LVGL and will continue to use it going forwards, but this has been incredibly frustrating.
