Then you might not object to having it work cross different hardware
either, right?-)

I ran cairo-perf on several different hardware and noticed that they
couldn't be compared with cairo-perf-diff-files since it uses the
ticks value for the comparison. The ticks can be very different on
different hardware, so I added an option to use the ms value instead.
This loses precision of course, but it should be small enough loss to
not really matter.

And getting something more or less descriptive is better than getting
lied to outright, right?-) The diff for example described the 770 as
over 800x faster than my 700MHz Celeron, which made me slightly
skeptic on the result...

I took the patch from Mr. Pihlaja (doesn't seem to be applied to git
head) and added my option to that. If someone would be kind enough to
check it and push it, I'd be greatful.

More on the results a bit later.
