Hi all,

Pixman is used as a bottom-layer backend for S/W rendering for various
applications and majority of the time is spent by pixman for rendering
intensive work. So providing performance information can help people
figure out hot spots and we can do optimizations based on the result.

This profiling tool is an extended version of siarhei's slow path
reporter and gathers performance data for each compositing paths and
report the result at the end of the program. You can include this tool
by giving --enable-perf-stat=yes option to autoconf and turn on by
setting PIXMAN_ENABLE_PERFSTAT environmental variable at runtime.


Best Regards,
Taekyun Kim
