 /** Set this path to the result of applying the Op to this path and the
     specified path: this = (this op operand).
     The resulting path will be constructed from non-overlapping contours.
     The curve order is reduced where possible so that cubics may be turned
     into quadratics, and quadratics maybe turned into lines.

     otherwise, result is unmodified.
