Skip testing of stencil textures where non-readable. Readback of stencil is not supported on vanilla ES, so we introduce a toggle to disable it. NVidia GLES drivers support NV_stencil_read and NV_depth_stencil_read extensions, so we use those where available. It turns out ANGLE supports NV_stencil_read but not NV_depth_stencil_read (for reading from the packed depth/stencil buffers which Dawn uses), so that's the extension we check for.

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
