+* Fill bucket and airbrush cursors are supposed to invert the background in parts. This is not possible with `.png` files. Microsoft Edge also apparently requires `.cur` files for custom cursors. I already have `.cur` files in the repo for the modern theme (unused), and extracted (outside the repo) for the classic theme. I just need to copy them, rename them semantically, use them, and do some testing to see if format fallbacks work as expected.
