Make that three. I see you also briefly mentioned the ordering of
concatenated matrix transforms, which I covered at length here
<http://cairographics.org/matrix_conventions/>.

Looking back at it, it’s certainly full of a lot of useful info. But I
think it’s too much for one page.

So we currently have that tutorial, and we have the cookbook
collection. I think it makes more sense to break out some of these more
tricky topics into the latter, and leave the overall tutorial
introduction as a shorter document, ending with a “where to get more
info” section.

Cairo’s support for paths is really pretty elementary. They are not
anywhere near first-class objects.
