Cursor can be very hard to see in some situations

[zb140]

In my setup, the mouse pointer is very small and doesn't contrast well with other stuff on the screen, so I often find myself losing track of where it is. From discussion in Discord it sounds like this is because of scaling at higher resolutions, which makes sense (I'm usually streaming at 2560x1600). This issue is to track adding some resolution-based scaling to the cursor so (hopefully) it'll be harder to lose.

Thought for the future: it'd be super awesome if there were a way to support standard XCursor themes so people could change the cursor appearance too. That way I could install a high-contrast theme if needed. A quick search around Google suggests the xcursor crate can help with that. But that's a much lower priority "maybe someday" feature 😄
