DYNAMIC_INDEXING is checked by default, since WGPU doesn't allow
for any kind of specialization constants and constant indexing is
nigh useless.
STORAGE_RESOURCE_BINDING_ARRAY is enabled iff the device supports:
- both or neither of uniform and buffer arrays with dynamic indexing;
- both or neither of sampled and storage images with dynamic indexing.
NONUNIFORM_INDEXING is enabled iff for ALL types of descriptor arrays
*that are supported for dynamic indexing*, nonuniform indexing is
also allowed.
These flags have a limitation in that some platforms
(eg.
https://vulkan.gpuinfo.org/displayreport.php?id=11692#features_core_12)
may support a strange subset of those features (example device
supporting non-uniform indexing for textures and storage buffers,
but NOT for storage textures or uniform buffers). In that case feature
will be reported as missing, even though it is partially present.
In the author's opinion, this flag set is convenient for the
users to query; however, due to aforementioned limitations, it would be
desirable to obtain statistics about "edge-case" platforms and what
percentage of reports they comprise.
1525: Add Naga bypass to allow feeding raw SPIR-V shader data to the backend. r=kvark a=ElectronicRU
**Connections**
Fixes#1520 .
**Description**
While Naga checking is undoubtedly very useful, it currently lags behind
what is possible in SPIR-V and even what is promised by WGPU (ie binding
arrays). This adds an unsafe method to wgpu::Device to allow feeding
raw SPIR-V data into the backend, and adds a feature flag to request a
backend supporting this operation.
**Testing**
`texture_arrays` example is runnable now, which uncovers an additional bug in Vulkan backend - binding arrays are instead treated like sole bindings, and indices shift, too. Lots of errors from validation layer ensue.

- Remove Cow from wgpu-hal API surface. You graze on in our hearts.
- Rename feature flag to SPIRV_SHADER_PASSTHROUGH in anticipation
of crate feature `spirv` to reduce confusion.
- Add some more documentation about behaviour and intended avenues of
use to the feature.
- rename ShaderInput variants
- rename feature flag
- hard error on Metal backend trying to compile SPIR-V
- fix test failing because of feature flag bits changing

1511: Added storage texture array support. r=kvark a=ElectronicRU
**Description**
Arrays of storage images (*f*image*n*D in GLSL parlance) should now be supported.
I also took the liberty to refactor texture format checking a bit,
and tighten up sampled texture support detection for Metal as well.
**Testing**
Not completely sure what's the proper testing approach here, open to suggestions.

* Add command buffer fill buffer method
* Added test for buffer fill
* Added image clear + test
* image/buffer clear methods are now pure clear to zero
* fix cargo clippy & int type issues
* clear buffer alignment is now given by COPY_BUFFER_ALIGNMENT
* joined buffer/image clear player tests
* ImageSubresourceRange is now used in TextureViewDescriptor
1391: Simplify features r=cwfitzgerald a=kvark
**Connections**
Fixes#1390
Makes vertex writable storage optional (native-only for now)
Fixes the follow-up to #891
**Description**
Refactors the code so that adding new features and maintaining current ones is much easier.
Refactors the way missing features are checked and reported, DRY way.
**Testing**
Not really tested
