TextureEncodingTest has two textures (SlotLabels.png, TestLabels.png) which are PNG files containing grayscale + alpha.

Looking at the specification, both pbrMetallicRoughness.baseColorTexture and material.emissiveTexture are RGB plus optional alpha. Is it expected that implementations expand grayscale to match the required components?

Yes. We should probably mention that in the spec.

Even better, I'll make a dedicated test case for that. Thanks for pointing out!
