Should we keep this more specific until we have a second use case?
CHROMIUM_stream_texture_matrix? That way we don't even need the enum value.

Also, can you add an extension spec file to gpu/GLES2/extensions/CHROMIUM for
this that describes what it does and how it should be used.

specific: sure, that's exactly how it was in PS4.  it thought you wanted the
enum + more general mechanism.  gladly removed.

extension spec: done.
