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

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):

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

GPU to ensure the depth result is correct.
