The coordinates of the new points and handles it produces seem to be rounded up to whole numbers, is this normal? http://www.drgs.no/dev/pointstocurves.jpg

Can this be fixed by changing some parameters here:
pointsToCurves(tolerance[, threshold[, cornerRadius[, scale]]])
Parameters:
tolerance: Number
threshold: Number
cornerRadius: Number
scale: Number

This function takes an array of points which you create or may have recieved
from CurvesToPoints. It also needs a curve fitting tolerance ( *tolerance).
This will basically determine the number of path segments created, the
higher the tolerance, the more approximate the fit. kAIRealOne will give
you the most exact fit, but also the most segments.
