fix wrong bucket calculation for western hemisphere, close to poles, full-degree...

set_bucket computed false left border, if the span was greater than 1, longitudes were less than zero
and longitudes were within SG_EPSILON on a full degree. Example: -179.0, +87.5 returned -176, 87
but should return -180, 87.
