Returns the direction to which the downward gradient is steepest. This implements the Deterministic 8 (D8) algorithm for identifying a single flow direction based on elevation data. Direction is numbered clock-wise beginning with 0 for the North. If no direction can be identified result will be a -1. If 'bDown' is not true the cell that the direction is pointing to might have a higher value than the center cell. If 'bNoEdges' is true a -1 will be returned for all cells that are at the edge of the data area.
