INTERPOLATION_PRECISION

#define INTERPOLATION_PRECISION   4

This factor determines how many times the order is over than the minimum required order. Higher values give less problems with aliasing but some amplitude errors. Lower values make less amplitude errors but more aliasing problems. This should be a good compromise...

INTERPOLATION_ZOOM

#define INTERPOLATION_ZOOM   0.10

If the zoom factor is below this margin, an interpolation will be used.
