1231: Added TextureFormatFeatures::filterable which may overwrite TextureSampleType::Float.filterable r=kvark a=Wumpf
**Description**
The expectation is that with `wgt::Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES` enabled, any texture format which is sampled as float may be (linearly) filtered if so supported by the adapter, not only those that the webgpu specification denotes as filterable.
This arguably causes a bit of a mess in the way we distinguish `sample_type` and `(guaranteed_)format_features`: The float sample type (via spec) essentially integrates a feature, namely if it is filterable or not. Unlike the actual format _type_ which is just a property of the format, this property may or may not be available depending on the device.
So the type of `sample_type` stays statically defined whereas the Float.filterable property suddenly becomes overwritten by a format_feature which may or may not be present. Couldn't come up with a cleaner solution so far.
**Testing**
Tested in project (blub) depending on R32F filtering - passing now what was previously causing
```
wgpu error: Validation Error
Caused by:
In Device::create_bind_group
note: label = `BindGroup: Narrow Range filter 1`
texture binding 1 expects sample type = Float { filterable: true }, but given a view with format = R32Float
```
(Blub still can't run on latest wgpu because of other reported issues)

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.
WebGPU
This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gpu-alloc and gpu-descriptor. See the upstream WebGPU specification (work in progress).
The implementation consists of the following parts:
- internal Rust API for WebGPU implementations to use
- Rust types shared between wgpu-coreandwgpu-rsplayer- standalone application for replaying the API traces, useswinit
This repository contains the core of wgpu, and is not usable directly by applications.
If you are looking for the user-facing Rust API, you need wgpu-rs.
If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
