snappedGridPoint as well as at all eight grid points around it using
horizontalSpacing and verticalSpacing of the gridInfo to determine their position.
If the spacing in view coordinates between the snappedGridPoint and any of these grid points is
smaller then the minimumSpacing, a grid point further away from the snappedGridPoint
is used instead to fulfill the minimumSpacing.
This way the snap result visualization adapts to the current zoom level but does place it's painted points only
on grid coordinates.
