pixman with and without SSE2 benchmarks?

[Matthieu Herrb]

Hi

Does someone have some benchmarks or numbers from real life X usage 
showing the benefits of using the SSE2 code in pixman 0.12.0 over non 
SSE2 on x86 and/or x86_64 cpus?

I'm asking because OpenBSD is stuck with an old gcc version which can't 
compile the SSE2 code, and I wonder if it's worth hacking something to 
be able ship a version compiled by gcc 4.2 or later with SSE2 support 
with OpenBSD binary distributions.

Thanks in advance.
