WIP: runtime switch for how to interpret SkColor -vs- srgb
Still very conflicted about the "right" way to proceed with this, but thought I'd experiment with a runtime flag, so we can practice seeing SKPs in various stages of "srgb correctness".
Other aspects to either fix, or at least provide runtime switches for:
- untagged images
- gradients
- colorshader
- drawVertices
