update resvg to latest, same with guillotiere

[aentity]

Hello, also to update resvg, which removes old deflate and old png, and many other deps in a tree.

[aentity]

Oh no, it looks that resvg has removed raqote and uses a "tiny skia" which is native build? maybe it's not good, i don't know.

Yeah, the dependencies of resvg have grown considerably. We may consider using an updated version once tiny-skia matures or whenever we implement a Skia renderer.

In any case, thanks for taking a shot at this. Closing for now!

Switched to resvg from git in my fork now: valpackett@a2d07cb (tiny-skia is all-Rust already)

It outputs RGBA instead of BGRA.. for now I just added the conversion right there using image, but it would be much better to "convert" in the fragment shader.

Code size of rustybuzz+tiny_skia+usvg+resvg in release mode is considerable, though wgpu+wgpu_core+naga+gfx_backend_vulkan+ash is still bigger :)

@myfreeweb Cool! Yeah, I saw the announcement of tiny-skia a while ago.

We are just waiting for a new resvg release at this point. Feel free to open a PR!
