distance

public static double distance(double x0,
                              double y0,
                              double x1,
                              double y1,
                              double ppvAspectRatio)

Computes XY distance in X units, allowing Y units to differ from X units by a linear factor. The ratio of X units to Y units is specified with ppvAspectRatio. This is useful when computing cumulative distance along a line-strip, for stippling.
