Right. We added a "--disable-some-floating-point" option, (or similar
name), when we found some code that improved performance on
non-hardware-floating-point systems but regressed performance on
systems with hardware floating-point.

*But* shortly after adding the option, (and before the first release
that included it), we found an alternate way to write the affected
code that was faster for both kinds of systems. So, so far, the option
doesn't actually change anything, (as far as I'm aware).

But if you are using a system with very poor performance for
floating-point operations then it certainly doesn't hurt to add that
option to your build configuration. And perhaps in the future it will
change something significant.

But for now, I don't think you'll find it affecting your bug.

Have fun with cairo!
