There seems to be many PRs relating to this issue, but they don't include all platforms and for some reason lost steam. This PR again tries to make this feature happen, and does it for all desktop platforms (x11, wayland, macos, windows, web). I think the best user of this feature and the reason I'm doing this is Bevy and game engines in general. There non laggy hardware cursors with custom images are very important. Game devs also like their PNGs so supporting platform native cursor files is not that important, but I guess could be added too.
