If changing +1 to +2 makes a difference then maybe you've got the
co-ordinates of your bounding box mixed up. What are you using?
It should be: minX, minY, maxX, maxY like...
bbox = (-180.0,-90.0, 180.0,90.0)
If you've got some negative values it is easy to get confused between
min & max. The min should be the most negative value, e.g.
bbox = (-20.0,-20.0, -10.0,-10.0)
