Update to wgpu 0.10

[parasyte]

• It would be nice to return an error from the render function

• imgui-winit is still a WIP (open PR: Upgrade to wpgu 0.10 Yatekii/imgui-wgpu-rs#66)

• minimal-fltk flashes wildly! :(

• Closes WGPU 0.10 #185

Just so I don't forget: I need to verify if pixels.surface_size is still necessary. The new wgpu::SurfaceConfiguration basically has the same information as our Surface struct (IIRC). We might be able to trim some fat!

Also need to remove all references to "swap chain", and consider adding SurfaceConfiguration to PixelsContext instead of recreating it every time.

Hi
Thanks for this. Regarding the fltk example, can you try replacing the:

        win.redraw();

        // Calls to redraw in the event loop require an explicit sleep
        thread::sleep(Duration::from_millis(SLEEP));

part of the loop with:

        app::flush();
        app::awake();

This seems to resolve the issue of flashing for me on Windows.

Thanks for the suggestion! I'll give this a shot tomorrow when I get back to resolving the other remaining issues.

Just converted a project over to this branch and it was a drop-in replacement. I think this is good to go.

... I'll address the imgui-winit example in another PR.
