Feature Request: Fractional scaling support

[songww]

The contents of the satellite window are blurry in niri with 2x scaling turned on.

It would be nice if the contents of the satellite window scaled properly like the window manager.

The latest version of Xwayland now properly supports scaling. Just need to start with the "-hidpi" parameter while launching, applications can work well using the GDK_SCALE environment variable.

Related: #28
Note that the -hidpi parameter is only for rootful xwayland.

+1 on this. It would be so awesome to at least have integer scaling work well.

as an appendage to this, even just letting xwayland render at native resolution would be super helpful even without the other scaling bits. I suppose this would be half of the solution necessary for fractional scaling?

I'm going to close this, as I think #28 will end up being something close to the path I take, and satellite technically exposes fractional scaling to Xwayland properly.
