36f133a5ae Use a modulo to keep the buffer position in range for looping sources
A high pitch and low buffer size can cause a lot of unnecessary iterations
otherwise, that just decrement the position

be292e5f0b Don't hold the whole-number position in the fractional value
This will help prevent overflows when the max pitch is increased

Should help with latency issues some people have and not put too much extra
burden on the mixer, hopefully
