OpenGL ES: implement compressed texture support. SwANGLE does not support GL_EXT_texture_compression_s3tc. However, it does support GL_EXT_texture_compression_dxt1, GL_ANGLE_texture_compression_dxt3 and GL_ANGLE_texture_compression_dxt5, which should be sufficient for Dawn's purposes. Note that sRGB formats may be problematic for OpenGL ES in general, but ANGLE does support them, so we can satisfy the requirements for Dawn's texture_compression_bc and exercise the codepaths on ES. glPixelStorei is not only unsupported for CompressedTexSubImage*D() but causes asserts in ANGLE and validation errors elsewhere. The fix is to scope the glPixelStorei() calls to the non-compressed codepath.

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:
