- Switch from legacy uniform semantics to uniform structs.
- Completely separate shader bundle from runtime stage.
- Packing multiple backends per shader.
- Pack struct and member fields into the shader bundle flatbuffer.
- Bind uniforms with correct metadata for GLES.
- Add uniform struct size and member offset reflection.

Okay, this is finally at a point where I'm mostly happy with it. I need to get a much less trivial example going to feel out how a fuller runtime reflection would work, if any (same would go for utilities like a swapchain/surface helper). Technically we don't actually need member reflection at all, since member alignment should be stable across the backends. |
