Disjoint(g1,g2)

Description
-----------

Returns 1 or 0 to indicate whether g1 is spatially disjoint from (does not
intersect) g2.

DISJOINT() tests the opposite relationship to INTERSECTS().

DISJOINT() is based on the original MySQL implementation and uses object
bounding rectangles, while ST_DISJOINT() uses object shapes.
