-/* Compare two slopes. Slope angles begin at 0 in the direction of the
-   positive X axis and increase in the direction of the positive Y
-   axis.
-
-   This function always compares the slope vectors based on the
-   smaller angular difference between them, (that is based on an
-   angular difference that is strictly less than pi). To break ties
-   when comparing slope vectors with an angular difference of exactly
-   pi, the vector with a positive dx (or positive dy if dx's are zero)
-   is considered to be more positive than the other.
-
-   Also, all slope vectors with both dx==0 and dy==0 are considered
-   equal and more positive than any non-zero vector.
-
-   <  0 => a less positive than b
-   == 0 => a equal to b
-   >  0 => a more positive than b
