Re: Using/requiring Cairo

[Paul]

I can't speak to the technical questions, but I see the appeal of this 
idea.  Cairo looks like a mature, well-supported, and widely-used library.

https://en.wikipedia.org/wiki/Cairo_%28graphics%29

Interestingly, "Cairo uses hardware acceleration 
<https://en.wikipedia.org/wiki/Hardware_acceleration>^[3] 
<https://en.wikipedia.org/wiki/Cairo_%28graphics%29#cite_note-3> when 
available."

I see that it can produce Postscript as well as PDF, among its various 
backends.  "The vector graphics application Inkscape 
<https://en.wikipedia.org/wiki/Inkscape> uses the Cairo library for its 
outline mode display, as well as for PDF 
<https://en.wikipedia.org/wiki/Portable_Document_Format> and PostScript 
<https://en.wikipedia.org/wiki/PostScript> export..."
