   - Hide previously public functions on SkImageFilter that were intended for internal use only

 * SkColorFilters::HSLAMatrix - new matrix color filter operating in HSLA space.

 * Vulkan backend now supports YCbCr sampler for I420 Vulkan images that are not
   backed by external images.

 * Add SkCodec::SelectionPolicy for distinguishing between decoding a still image
