LGTM

Would a reflection test for this in compiler_unittests.cc make sense?

Nit: Keep default to SourceOver? Although advanced blends are more contentious, so maybe someone flipping through is more likely to notice a problem with Screen as the default.

Yeah, just thought defaulting to the advanced ones was more likely to throw up issues.

Oh, convenient!

My hope is that the pipeline creation itself would be the ultimate fix. Another patch incoming that wires up the advanced blend libraries.

Do we know how this change had previously broken GLES and how this changed fixed it?

The original issue was light on details but there is now a separate CreateGLSLCompiler which is probably what's used. So this change shouldn't affect GLSL at all. I believe earlier there used to be a common compiler instance creation and I can believe was hard to configure just right for one backend without causing unintended consequences elsewhere. But again, the issue was light on details so its hard to say. I'll keep an eye out for repercussions.
