The Skia project doesn't do releases, and so does not have any version
numbers.  We can identify the git SHA we based our support on, but
that's about it.

I don't know when version 1.0.0 was declared but I think it was a long,
long time ago, so testing it in our configure is not going to be useful.

Whereas Cairo aims to be a general purpose library used by everyone,
Skia's development mainly just focuses on its use by one program -
Chromium.  Because of this, API stability is not a priority for them.
(I think this is the same reason they don't do releases.)

Sounds good.  I'll wait on pulling the patch for now.
