This parameter list makes me think we should've taken an SkBitmap (or an
SkPixmap?) as a parameter. (Doesn't need to be in this CL, but something to
consider?)

I agree this would make sense: PNG codec has some encode helpers that take a
SkBitmap parameter.

Yeah I think it should take an SkPixmap.  SkBitmap would be fine as well, but I
think Skia in general is trying to move towards SkImage and SkPixmap.
