Well, it can be used in write_to_png too. Donno about SVG, but that has
some support for compression too I assume?
This is a common theme that we have not quite addressed in cairo yet:
what gets into the common namespace and what into backend-specific ones?
cairo_show_page() for example is as much PS/PDF dependent that
compression_level is. SVG's restrict_to_version is different in that
you /cannot/ have a non-SVG-specific for it, as in, you need enum values
that are named SVG-something. But for compression level, or page, you
can name them and describe their action without referring to any
specific backend. That's my compass.
