"Origin" means *the* origin (0,0), not the start of the curve. Note that no checks are made on the start and end positions of the curve; this function only checks the inside of the curve. Args: p0 (complex): Start point of curve. p1 (complex): First handle of curve. p2 (complex): Second handle of curve. p3 (complex): End point of curve. tolerance (double): Distance from origin. Returns: bool: True if the cubic Bezier ``p`` entirely lies within a distance ``tolerance`` of the origin, False otherwise.

A quadratic spline is specified as a list of points. Either each point is a 2-tuple of X,Y coordinates, or each point is a complex number with real/imaginary components representing X,Y coordinates. The first and last points are on-curve points and the rest are off-curve points, with an implied on-curve point in the middle between every two consequtive off-curve points. Returns: The output is a list of tuples of points. Points are represented in the same format as the input, either as 2-tuples or complex numbers. If ``quads`` is empty, returns an empty list. Each tuple is either of length three, for a quadratic curve, or four, for a cubic curve. Each curve's last point is the same as the next curve's first point. Args: quads: quadratic splines max_err: absolute error tolerance; defaults to 0.5 all_cubic: if True, only cubic curves are generated; defaults to False Raises: ValueError: if an input spline has fewer than 3 points, or if adjacent splines do not connect end-to-start. rc&g|]}d|DS)c4g|]\}}t||Sr)complex)r(xys rr)z2quadratic_to_curves...s$000FQ'!Q--000rr)r(r=s rr)z'quadratic_to_curves..s'@@@Q00a000@@@rr%r*r&Nc@g|]}td|DS)c32K|]}|j|jfVdSN)realimag)r(cs r z1quadratic_to_curves...s+88Q(888888r)tuple)r(r1s rr)z'quadratic_to_curves..s/MMMU%88%88888MMMr) rKrHtyperTrEr+r;r,r?popextendspline_to_curves) rNrJrOrGrMr>costsrLr=r5qqr-s rr r sP   )))((''''eAhqk""g-J A@@%@@@ q!
