it always has been hard, until Chris Wilson's recent cairo-perf-trace.

+## Previous attempts at 2D benchmarking
Various attempts at 2D-rendering benchmark suites have appeared and
even become popular. Notable examples are x11perf and gtkperf. My
things like x11perf in the past. I won't recommend it again in the
future. See below for what I suggest instead.

For 3D performance, everybody knows this lesson already. Nobody
measures the performance of "draw the same triangles over and
coding up application-specific benchmarking code for every interesting
application isn't something that anyone is signing up to do right now.

Over the past year or so, Chris "ickle" Wilson has been putting a lot
of work into a debugging utility known as cairo-trace, (inspired by
evolution. Obviously, anyone should feel free to generate and propose
new traces to contribute.

In the few days that cairo-perf-traces has existed, we're already
seeing great results from it. When Kristian Høgsberg recently proposed
