int orientation(const real ray& r, const real point& p)<br />

int cmp slopes(const real ray& r1 , const real ray& r2 )<br />

computes orientation(a, b, p) (see the manual page<br />

of real point), where a ≠ b and a and b appear in<br />

this order on ray r.<br />

returns compare(slope(r 1 ), slope(r 2 )) where<br />

slope(r i ) denotes the slope of the straight line<br />

underlying r i .
