Syntax
------ 
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.
