Wgpu

- 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`.

wgpu-types-0.8.1 (2021-06-08)

- fix dynamic stencil reference for Replace ops

In this release the API is aligned with the latest webgpu.idl, and
we updated to the latest release of wgpu-native (v0.14.2.3).

Changed:

* To use the default `min_binding_size` in `create_bind_group_layout`, it should be `None` instead of zero.
* If the depth-stencil texture has not room for stencil data, the `stencil_read_mask` and `stencil_write_mask` fields in the `DepthStencilState` struct passed to `create_render_pipeline()` must be set to 0.
* In WGSL, `stage(compute)` must now be `compute`. Same for `vertex` and `fragment`.
* In WGSL, the list of reserved words has been extended, including e.g. `mod`, `matrix` and `ref`.
* In WGSL, `smoothStep` is now `smoothstep`.

Added:

* New IDL: texture has new props `weight`, `height`, `depth_or_array_layers`.
* New IDL: Buffer has new prop `map_state`.

Fixed:

* The offscreen canvas's mainloop prevents leaking callbacks better (322)
* Prevent error messages when Qt examples/apps are closed (326)

Fixed:

* Prevent Qt warning about setting dpi awareness (320)
* Make canvases close when they get deleted (319)
* Fix qt canvas in ipython (315)
* Make offscreen canvas closable (309)
* Fix that the offscreen canvas had it size hardcoded, ignoring the given size (317)
* Fixed renaming of `queue` in docs (308)
* Fix using `.draw_frame` on qt canvas (304)
* Add missing dev dependencies (295)

Added:

* A shadertoy utility, plus examples (312)

Changed:

* Improve the error prompt when wgsl code is multi line error (311, 316)
* Tests: execute examples in the test process (310)
* Package only the release binary (not the debug build) (299)
* Codegen: uses in-memory file system during code generation (303)
* Improve readme (290, 302, 314)

Fixed:

* Fixed imports for PyQt6.
* Keyboard events work again for Qt 6.3.
* Fixed that overloading ``handle_event()`` did not work for a canvas based on a Qt or wx main widget/window.

Added:

* Can now add a wildcard ("*") to ``add_event_handler`` to handle all events.
* Shader error messages show more context, making shader debugging much easier.
* VSync can now be turned off to raise the frame rate when needed. Note that FPS measurements are still a poor performance benchmark!

Changed:

* GLFW canvas does not draw when minimized anymore.
* The offscreen and Jupyter canvas now use the srgb format for consistency with normal canvases.
* The examples have been adjusted for srgb colors.

Fixed:

* Fixed regression that `canvas.handle_event()` could no longer be overloaded to handle move and wheel events.

Changed:

* Added a note in the docs to explain that the version of the examples must match the runtime version.
