  * performance hack: exploit the fact that the x coordinates (diameters) of the hull in DIRECT fall into only a few different values (although this may change in future modifications); also, we weren't handling the case of equal (x,y) points correctly in the hull code

    M ./cdirect/cdirect.c -6 +49
