This only changes behavior when the input SkBitmap/SkPixmap is
tagged with a non-null SkColorSpace. Android tags their bitmaps
as sRGB when linear blending is enabled. So this only changes
behavior in Android when linear blending is turned on.
*If linear blending is turned on, this will do a color correct
encode (which is the desired behavior).
*If linear blending is turned off, this will do a legacy encode.
TODO: Add support for F16.
TODO: Add color space support to WEBP.
TODO: Tag encoded images with ICC profiles (when it makes sense).
