Module gr_bezier

    gr_bezier - a GRToolbox module
    Calculates bezier curves. Input points
    will be taken as controlpoints for the casteljau algorithm.
    The degree of the curve is given by -r.  The resulting curve
    is continous.
    Each bezier curve will have the same number of points given
    by the -n option.
    degree+1 controlpoints are taken for each piece of curve
    Two neighbored curvepieces share on controlpoint, so  altogether
    #pieces * degree +1 controlpoints are neded. The number of input points
    should match this number.
    -[n rh o v noc nof now skip f m c e i s l]
    -help    For help on all options.
Special Options:
    -n int     number of points for each curve patch.
    -r int     degree of the bezier curve
