winit-wayland: add new font backend features

[HigherOrderLogic]

As title.

P/s: Sctk-adwaita has added new skrifa and cosmic-text backend for text rendering, do we want to add those as features of winit-wayland?

• Tested on all platforms changed
• Added an entry to the changelog module if knowledge of this change could be valuable to users
• Updated documentation to reflect any user-facing changes, including notes of platform-specific behavior
• Created or updated an example program if it would help users understand this functionality

I guess we can add features just for completeness 🤔

[HigherOrderLogic]

Seems like CI failures are due to new Syn v3.

It would be nice to also add feature flags to select the recently added font renderer options:

• Add skrifa font rendering backend PolyMeilex/sctk-adwaita#91
• Add cosmic-text title renderer (shaping + font fallback) PolyMeilex/sctk-adwaita#98

Just like the preexisting one for crossfont.

EDIT: Ah sorry it's already there... 😶 Awesome!

[HigherOrderLogic]

I already added it.

I think the only blocker right now is figuring out which deps need to be upgraded to pass cargo-deny.

[torokati44]

Yep, just noticed now, sorry for the noise!

Imo we better wait for a new cosmic-text release with skrifa bumped. This repo doesnt have a Cargo.lock so I dont think that command will work.

This repo doesnt have a Cargo.lock

Interesting to have a deny check then as cargo will just pick the maximum version possible rather than unify the versions. One may almost claim this is incorrect use of cargo deny. It is not like there isn't a solution with a single version, just that cargo doesn't bother to find it.

Anyway, hopefully there will be a range for cosmic-text and then this will not be a problem (as long as the upper limit is the same...).

[torokati44]

Also, I think the recommendation has been for a while now to also have Cargo.lock checked in for library crates.

[kchibisov]

We bumped sctk-adwaita to 0.12.0 can you just rebase it to add features?

[kchibisov]

You need to handle cargo-deny one way or another since it's from your changes.

[HigherOrderLogic]

Should I just skip it in deny.toml then?

[kchibisov]

well, skip + add comment why.
