Description: Describe your changes here...

Fix for the issue on sdgrid that resulting map extent expands or shrinks when cell size is calculated by the task.
A cause of the issue is that the task always takes 10% margin when it calculates cell size automatically. In this fix, margin is set to 1 pixel.
