* padBuffersToMaxVertexAttribStride (Vulkan workarounds) (http://anglebug.com/42263049): Disabled
condition: isAMD || isSamsung
Vulkan considers vertex attribute accesses to count up to the last
multiple of the stride. This additional access supports AMD's robust
buffer access implementation. AMDVLK in particular will return incorrect
values when the vertex access extends into the range that would be the
stride padding and the buffer is too small. This workaround limits
GL_MAX_VERTEX_ATTRIB_STRIDE to a maximum value and pads up every buffer
allocation size to be a multiple of the maximum stride.

* lazy_clear_resource_on_first_use:
(https://crbug.com/dawn/145):
Clears resource to zero on first usage. This initializes the resource so
that no dirty bits from recycled memory is present in the new resource.
* use_temporary_buffer_in_texture_to_texture_copy:
(https://crbug.com/dawn/42):
Split texture-to-texture copy into two copies: copy from source texture
into a temporary buffer, and copy from the temporary buffer into the
destination texture when copying between compressed textures that don't
have block-aligned sizes. This workaround is enabled by default on all
Vulkan drivers to solve an issue in the Vulkan SPEC about the
texture-to-texture copies with compressed formats. See #1005
(https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more
details.
* vulkan_use_d32s8:
(https://crbug.com/dawn/286):
Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When
available the backend will use D32S8 (toggle to on) but setting the toggle
to off will make it use the D24S8 format when possible.
* vulkan_use_s8:
(https://crbug.com/dawn/666):
Vulkan has a pure stencil8 format but it is not universally available.
When this toggle is on, the backend will use S8 for the stencil8 format,
otherwise it will fallback to D32S8 or D24S8.
* disallow_spirv:
(https://crbug.com/1214923):
Disallow usage of SPIR-V completely so that only WGSL is used for shader
modules. This is useful to prevent a Chromium renderer process from
successfully sending SPIR-V code to be compiled in the GPU process.
* use_placeholder_fragment_in_vertex_only_pipeline:
(https://crbug.com/dawn/136):
Use a placeholder empty fragment shader in vertex only render pipeline.
This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and
serves as a workaround by default enabled on some Metal devices with Intel
GPU to ensure the depth result is correct.
* timestamp_quantization:
(https://crbug.com/dawn/1800):
Enable timestamp queries quantization to reduce the precision of timers
that can be created with timestamp queries.
* use_vulkan_zero_initialize_workgroup_memory_extension:
(https://crbug.com/dawn/1302):
Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan
extension VK_KHR_zero_initialize_workgroup_memory is supported.

Disables the use of indexed draw buffer state which is unsupported on some

Call glFlush before glClientWaitSync to work around bugs in the latter

Disallow usage of SPIR-V completely so that only WGSL is used for shader

* use_blit_for_buffer_to_stencil_texture_copy:
(https://crbug.com/dawn/1389):
Use a blit instead of a copy command to copy buffer data to the stencil
aspect of a texture. Works around an issue where stencil writes by copy
commands are not visible to a render or compute pass.
* use_blit_for_depth16unorm_texture_to_buffer_copy:

Use a blit instead of a copy command to copy depth aspect of a texture to
a buffer.Workaround for OpenGL and OpenGLES.
