I ran a little test to get some speed numbers.  And the floats
won; about 2 - 2.5 % faster.
	The test was writing 10000 buffers full of sound using an
interpolating oscillator.  This is on a Mac 7500 PPC at 100Mhz without a
cache.  I admit suprise because I had been told that doubles were faster,
but I guess not.
