Wgpu

Fixed:

* Fixed setting the dpi awareness in the Qt backend, by correctly looking up the Qt version.

Changed:

* Links to readthedocs now point to *stable* instead of *latest*, so that people
reading the docs see these that reflect the latest release.
* Don't enable any features by default (previously WGPUNativeFeature_TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES was enabled).

Fixed:

* Fixed issue related to winid (native widgets) on embedded Qt widgets on Windows (348).
* Fixed our example screenshot tests.

Changed:

* The offscreen `WgpuCanvas.draw()` method now returns a `memoryview` instead of a numpy array.
* The shadertoy util changed internally from using numpy to using a memoryview.

Fixed:

* Fixed that `get_preferred_format()` could crash (in `wgpuSurfaceGetSupportedFormats`) due to an upstream bug in wgpu-native (342)

Added:

* The shadertoy util now supports GLSL, so code from the shadertoy website can be directly copied and run with wgpu (343)

Changed:

* Improved documentation.

Added:

* Added `print_report()` to get a report on the internals of wgpu.
* Added `command_encoder.clear_buffer()`
* Added support for GLSL.

- Updated:
- naga to `v0.5`.
- Added:
- `Features::VERTEX_WRITABLE_STORAGE`.
- `Features::CLEAR_COMMANDS` which allows you to use `cmd_buf.clear_texture` and `cmd_buf.clear_buffer`.
- Changed:
- Updated default storage buffer/image limit to `8` from `4`.
- Fixed:
- `Buffer::get_mapped_range` can now have a range of zero.
- Fixed output spirv requiring the "kernel" capability.
- Fixed segfault due to improper drop order.
- Fixed incorrect dynamic stencil reference for Replace ops.
- Fixed tracking of temporary resources.
- Stopped unconditionally adding cubemap flags when the backend doesn't support cubemaps.
- Validation:
- Ensure that if resources are viewed from the vertex stage, they are read only unless `Features::VERTEX_WRITABLE_STORAGE` is true.
- Ensure storage class (i.e. storage vs uniform) is consistent between the shader and the pipeline layout.
- Error when a color texture is used as a depth/stencil texture.
- Check that pipeline output formats are logical
- Added shader label to log messages if validation fails.
- Tracing:
- Make renderpasses show up in the trace before they are run.
- Docs:
- Fix typo in `PowerPreference::LowPower` description.
- Player:
- Automatically start and stop RenderDoc captures.
- Examples:
- Handle winit's unconditional exception.
- Internal:
- Merged wgpu-rs and wgpu back into a single repository.
- The tracker was split into two different stateful/stateless trackers to reduce overhead.
- Added code coverage testing
- CI can now test on lavapipe
- Add missing extern "C" in wgpu-core on `wgpu_render_pass_execute_bundles`
- Fix incorrect function name `wgpu_render_pass_bundle_indexed_indirect` to `wgpu_render_bundle_draw_indexed_indirect`.
