I don't think there would be any advantage to going from your current
code, through PostScript, then through some not-yet-existing code that
would generate cairo calls from the PostScript content.

That would involve a pile of code that doesn't exist yet, and wouldn't
necessarily be as efficient as you'd like anyway.

So much better would be to just write your code to call cairo itself,
(and as you say, it mirrors the PostScript operators quite well, so it
shouldn't be too difficult).

And once you have that, you might even find that you can throw away
your current PostScript-generating code and let cairo take care of
that part of the problem as well.

Let us know how things go or if you need any further help.
