Basic pipeline blend mode strength reductions:
- when the shader is opaque, srcover becomes src
- don't load dst when blitting in src mode with full coverage
- fold coverage into src alpha when in srcover mode
It's not obvious that we can fold coverage into src alpha when using a 565 mask, so I've not attempted that. What would we do about alpha?
Over all GMs this causes a single 1-bit difference in sRGB mode. No 565 or f16 diffs.
