What are the skia fixes this is blocked on?

Why the expected test results with FAILs in them?

This loop is unfortunate. Is there no way we could turn this into: return gMapBlendOpsToXfermodeModes[blendMode]

The core graphics libraries don't follow the blending modes exactly. I'm trying to get Apple to fix them.
If they won't fix them, I will have to put platform specific test results in.

I agree. I followed the example right under my new code that sets up the compositing

Sorry, from now on I'll make sure to clear flags as I migrate bugs.
