Add Vulkan to Freya's feature combo

[marc2332]

Hey @pragmatrix !

Would it be possible for you to create a new combo for prebuilt binaries (or maybe just update?) with the following features? I'd like to experiment with Vulkan support in Freya

Windows: ["gl", "textlayout", "svg", "vulkan"]
Linux: ["gl", "textlayout", "svg", "vulkan", "x11", "wayland"]
macOS: ["gl", "textlayout", "svg", "vulkan"]

Thanks again 😄 !

Hello @marc2332,

I'd like to experiment with Vulkan support in Freya

I'm happy to add new binaries, but first I'd like to know what has changed since #822. Are there blockers that prevent you using a local build for experimentation until you conclude that you want to release and maintain freya with vulkan and gl support?

[pragmatrix]

Could be related to this one #314:

A workaround is to move the source directory to the same drive as your rust installation, or vice versa.

and

WARNING at the command-line "--args":1:662: Build argument has no effect.

should be fixed in 0.72.0

I was able to get it working but now I find the vulkan API quite hard to understand without a proper example, is there any out there that integrates with winit and skia? I see there is one using ash but it's not using winit

It requires a decent amount of glue, but ash is great. For Slint you can take a look at https://github.com/slint-ui/slint/blob/master/internal/renderers/skia/vulkan_surface.rs .

[pragmatrix]

Skulpin uses skia-safe together with ash and winit. Dependencies are quite outdated, though.

Wew! It really is hard to set up, I'll try again asap, all the glue is killing me. Thanks to both of you!
