The lathe object can use linear, quadratic, cubic and bezier splines. The
SOR object uses some unnamed spline type.
  I have some questions.

  Suppose that I want to draw (just in a plain 2D graphic window) a qudratic,
cubic or bezier spline given the control points.
  Can someone tell me the algorithm used to calculate the curve for each type
of spline? Preferably I would like to get all the points that will form a
contiguous curve in the drawing bitmap (no gaps and no points drawn in the
same place) given the resolution of the drawing window, but also a less
perfect solution is ok.

  Also I would like an algorithm to draw the spline curve used by the SOR
object, given the control points.
