### prdl_CheckConic

Given the three vertexes of the conic triangle and the sharpness, this routine converts the conic to a Bezier curve and outputs the appropriate PostScript code to append the conic to the current path.

First the conic is subdivided at the parameter t = 1/2. If the sharpness of the subdivided conic is large, it is subdivided further.
