Efficiently moving things around in zig-zag Graphics buffer visualized w/ 24/32 bpp displays / neopixel strings

The modified items aren't flags - they're actual X/Y coordinates of the modified area - so I'm not sure it makes sense to put them together? Or you mean to move cursorX/Y to earlier in the struct, so they are always in the same place?

I guess for what you're doing you're unlikely to have to look any further than bgColor though?
