Also moves the TerribleCommandBuffer to utils:: because it isn't part of
the implementation of the wire, renames dawn::wire to dawn_wire, moves
src/wire to src/dawn_wire and puts the interface of dawn_wire in
src/include/dawn_wire.
The interface exposed by libdawn_native is declared in the new headers
living in src/include/dawn_native so that they both the users and the
libraries use the DAWN_NATIVE_EXPORT macros.
This removes the following for both Buffer and Texture:
- The builder's SetInitialUsage
- The object's FreezeUsage and TransitionUsage methods
- The CommandBuffer Transition<Object>Usage methods
All samples and tests are simplified as a result. This also obsoletes
the UsageValidationTest which is removed.
Some validation was dependent on "current usage" and hasn't been
reintroduced for implicit transitions yet:
- Buffers can be used while mapped
- Swapchain textures can be used after they have been presented.
Validation for these will involve collecting all the resources used by a
command buffer and will be done in a follow-up patch.
* Use a descriptor for BindGroupLayout
* Fix MatchesLambda
* Add WireTests.StructureOfStructureArrayArgument
* Add BindGroupValidationTests.BindGroupLayoutCache
I know there was some churn on which version of this shader was correct - but right now, this goes from broken on all 4 backends to working on all 4 backends. So this seems better.
The old code (accidentally?) uses descriptor arrays (I think), which are not trivial to support on all backends, so we won't use them for now.
However keep the following samples:
- CHelloTriangle that demonstrates the C API
- CppHelloTriangle that demonstrates the C++ API
- Animometer that matches the WebGL benchmark
- HelloDepthStencil that does more than just a triangle, renamed
to CubeReflection
- ComputeBoids as a cool graphics and compute interop demo
- glTFViewer that shows slightly more advanced usage of NXT
We are changing all object creation to use descriptors but there is no
creation argument to pass for queue, so instead Device::CreateQueue
takes no argument.
This as an API change to get closer to the direction in which WebGPU is
headed. The API change in next.json caused a ton of files to be changed
in the same commit to keep things compiling.
API: the Framebuffer and RenderPass objects are now merged in a single
RenderPassInfo that contains the attachments, loadOps and clear values
for a BeginRenderPass command. The concept of subpass is removed.
The RenderPass creation argument to RenderPipelines is replaced by
explicitly setting the format of attachments for RenderPipeline.
Validation: SetPipeline checks are changed to check that the attachments
info set on a RenderPipeline matches the attachments of the render pass.
Backends: Most changes are simplifications of the backends that no
longer require and indirection to query the current subpass out of the
render pass in BeginSubpass, and don't need to get the attachment info
from a RenderPass when creating RenderPipelines. In the Vulkan backend,
a VkRenderPass cache is added to reuse VkRenderPasses between
RenderPassInfos and RenderPipelines.
Tests and examples: they are updated with the simplified API. Tests
specific to the Framebuffer and RenderPass objects were removed and
validation tests for RenderPassInfo were added.
Tested by running CppHelloTriangle on all backends, end2end tests on all
platforms and all examples on the GL backend.

This is due to restrictions in HLSL. The size of RWStructuredBuffer<T> elements in Shader
Model 5.1 cannot be larger than 2048 bytes so we cannot use a
RWStructuredBuffer<Arr>, where Arr is a struct containing a large array.
This fixes the issue where the default texture wasn't uploading
correctly (due to 3f47729, changes in row pitch validation) by just
removing the broken texture entirely.
