Update to wgpu 0.10

[niklaskorz]

Updates wgpu dependency to 0.10 and fixes breaking changes in the code.

The PR was still in draft status. Do you want to add something? Or should I merge it?

[niklaskorz]

I'm experiencing some issues with the rendered frames, they are way too dark (see https://github.com/niklaskorz/linon/). Not entirely sure if it's an issue in my project or in the egui wgpu backend. Still investigating, so I put it in draft mode for now.

[hasenbanck]

I'm not using egui anymore, so I can't assist you with debugging. I'm just maintaining the PRs and the release process.

[niklaskorz]

So it's looks like an issue in the egui wgpu backend code, might be related to the sRGB conversion...

wgpu 0.10:

wgpu 0.9:

What does it do when you change:

    let mut sc_desc = wgpu::SwapChainDescriptor {
        usage: wgpu::TextureUsage::RENDER_ATTACHMENT,
        format: OUTPUT_FORMAT,
        width: size.width as u32,
        height: size.height as u32,
        present_mode: wgpu::PresentMode::Mailbox,
    };

    let mut sc_desc = wgpu::SwapChainDescriptor {
        usage: wgpu::TextureUsage::RENDER_ATTACHMENT,
        format: adapter.get_swap_chain_preferred_format(&surface).unwrap(),
        width: size.width as u32,
        height: size.height as u32,
        present_mode: wgpu::PresentMode::Mailbox,
    };

In the example?

[niklaskorz]

The outcome is the same, unfortunately.

Disabling the sRGB conversion in the shader doesn't look right either:

@niklaskorz select() order of true/false was swapped in naga 0.6. This should fix "dark" output.

That's it! Thanks a lot @Gordon-F

Ready to merge :) @hasenbanck
