示例1: write_eps_quadratic_edge
/** Write quadratic edge shape in PostScript format.
*
* Given the three points composing a quadratic mesh edge,
* write the cubic Bezier curve of the same shape in
* PostScript format. The formulas for P1 and P2
* at the start of this function will result in the cubic
* terms of the Bezier curve dropping out, leaving the
* quadratic curve matching the edge shape function as
* described in Section 3.6 of Hughes. (If you're attempting
* to verify this, don't forget to adjust for the different
* parameter ranges: \f$ \xi = 2 t - 1 \f$).
