Yes, what I mentioned is still what we need to do.
So the question is - is that "uniform Locals" the constant buffer associated with a render target (and changed at the render target frequency)? If so, can we call it something more descriptive than "Locals"?

I think we have a misunderstanding here, in #345 https://github.com/szeged/webrender/issues/345 . you mentionedWebRender has it associated with the target, so we can safely move it into a constant buffer within the per-target descriptor set.

@kvark I've removed the descriptor binding related changes (I will make that in a different PR, updated #335 for that), added the change to set the uniforms on a per render target basis. I will squash the commits after the review.
That's right.
