Introduce cairo_surface_observer_t for performance analysis
Another logging passthrough surface that records the style of operations
performed trying to categorise what is slow/fast/important.
In combination with perf/cairo-analyse-trace it is very useful for
understanding what a trace does. The next steps for this tool would be
to identify the slow operations that the trace does. Baby steps.
This should be generally useful in similar situations outside of perf/
and should be extensible to become an online performance probe.
