More SkCSXformCanvas work.

  - handle color arrays in drawPatch(), drawVertices(), drawAtlas()
  - color filters

Color filter support is a one-off for SkModeColorFilter.  I don't know
any other color filters that are parameterized by a color.  If there are
any/many, we may want to wire up something more comprehensive here.
