This PR improves support for gradients with alpha components. Fixes #1636.
The implementation in #1634 supported simple cases, but didn't support cases where the RGB components and alpha components had different color stops (not supported in a single
CAGradientLayer). The main thread engine works around this by rendering two different gradients -- one for the RGB color components, and another for the alpha components that masks the color gradient. This PR adopts that technique for the Core Animation rendering engine.
