    /* Convert the quadratic Beziers to cubic Beziers.
       The parametric eqn for a cubic Bezier is, from PLRM:
       r(t) = at^3 + bt^2 + ct + r0
       with the control points:
       r1 = r0 + c/3
       r2 = r1 + (c + b)/3

       A quadratic Bezier has the form:

       So equating powers of t leads to:
       r1 = 2/3 p1 + 1/3 p0
       r2 = 2/3 p1 + 1/3 p2
