Summary: use single-precision math functions on Mac OS X

Initial Comment:
On Mac OS X, Pd is using the double precision math functions even though Pd uses single precision floats.  You can see it here:

Here's a previous discussion on this:

I don't think this would make a massive difference overall, but I'll bet it would make a significant difference for any patch using sin, cos, atan, atan2, sqrt, log, exp, fabs, or pow.
