Behdad put a reference to it in util/README and the plan is to move the
tracing utilities into util during this dev cycle. I'll probably do that
in the next couple of days.

At the moment the core tracing utility is cairo-trace
[http://cgit.freedesktop.org/~ickle/cairo-trace/], and I'm developing an
experimental frontend as a means to extract test cases and just
generally inspect state. But for the time being, my favourite method of
invocation is:
$ cairo-trace --script program arguments
which will generate CairoScript output to the terminal and to a
program.$pid.trace file.
