Implementation of the final two functions.
Fix some typos I had previous made.

This code is working now, but it wasn't working an hour ago, and I didn't really do anything to fix it. I want to make sure I understand what's going on before this is merged. But it's rather straightforward code.

The naga bug is back.

This code is waiting for a new wgpu-native-lib to include:

gfx-rs/wgpu-native#432
gfx-rs/wgpu#6194

We pull directly from wpgu-native, so their next update should include the change. I'm not sure how wgpu-native decides which version of wgpu to use.

I'm not sure how wgpu-native decides which version of wgpu to use.

Here's an example: gfx-rs/wgpu-native#402 Basically bumping versions in cargo.toml and then making the necessary changes. It usually updates for each release of wgpu-core.

@almarklein.

I ask because it seems that tag 22.1.0.5 was created on gfx-rs/wgpu-native on Sept 12.

Meanwhile I don't see any tags on gfx-rs/wgpu, and the fix was merged into "trunk" on Sept 2. But it doesn't seem to have made it into the build of lib-native.

[almarklein]

That's correct. The latest tag from wgpu-core is 22.1.0. The versioning of wgpu-native is to take the version of wgpu-core and add a fourth number to it. We've had a few releases (22.1.0.x) for bugfixes and changes to how the binary archives are composed.

I've confirmed that this code works with a patched wgpu. I've tried it out both on emulated GPUs and on real GPUs.

I just need to wait for us to catch up.

[fyellin]

Do we have any news as to when there will be a new wgpu-native? This PR needs big foxes there in order to work.

[fyellin]

I see that gfx-rs/wgpu has just released v 23.0.0. Now I just need to wait for wgpu-native to incorporate that, and then for us to incorporate wgpu-native.

The work has started some time ago: gfx-rs/wgpu-native#441
