My hit-and-run opinion is that the FileSurface type is extraneous.
Just because those surfaces have similar-looking (or even identical)
constructors, doesn't mean that they need to share a base class.

Since this "FileSurface" has no representation in the cairo code,
cairo could always add a "FigSurface" (say) that is a file surface
in some ways, but not a FileSurface in every way, and then you'd 
be in trouble.
