overrideprivatevirtual

Given a src surface's color type and its texture info as well as a color type the caller would like read into, this provides a legal color type that the caller can use for readPixels. The returned color type may differ from the passed dstColorType, in which case the caller must convert the read pixel data (see GrConvertPixels). When converting to dstColorType the swizzle in the returned struct should be applied. The caller must check the returned color type for kUnknown.

We currently don't have an SkColorType for a 3 channel RGB format. Additionally the current implementation of raster pipeline requires power of 2 channels, so it is not easy to add such an SkColorType. Thus we need to check for data that is 3 channels using the isRGBFormat return value and handle it manually
