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.

The performance tools build system for Win32 hasn't been maintained
for some time. The makefiles are now structured as in other
directories (Makefile.sources used by both Makefile.am and
Makefile.win32) and some additional code hides os-specific parts.
