Pointer Events

[waywardmonkeys]

This is a draft as I think it is something people may want to comment on.

It is currently only on Windows, but I'll probably push a commit with Mac support soon (within the next day or three).

It doesn't do any extra features yet like multiple pointers. That requires using the raw input API on Windows, I think. (But that can happen separately.)

Once #126 lands (or is rejected), I'll update this via rebase to remove the extra stuff from here.

There's interesting questions once multiple pointers are supported, like how the capturing code should handle that.

I don't have any fancy Windows input devices.

This looks fine to me, with or without mac support. Getting all the backends ported to the pointer API (even without actual multi-pointer support) will let us get rid of the old mouse API

Yes, the equivalent version of this for Mac should be easy to knock out.

And yeah, I'd chase this with a PR to remove the old mouse API. Need to do some outreach to Lapce to get them to switch over as well and someone will have to tackle Xilem. (I've got a PR open there to get Xilem at least on the current version of Glazier: linebender/xilem#118)

@jneem I've flagged this as ready for review / landing. It handles both macOS and Windows for the basic conversion.

Web backend doesn't compile at all, so I'll handle it separately.
