Change YIncreasesUpwards Name/Definition

[Chris3606]

Currently, Direction offers a YIncreasesUpwards flag which effectively lets you set the coordinate origin to graphics-style origin (top left is (0, 0)), or cartesian coordinate plane origin (bottom-left is (0, 0)).

I propose changing this flag to be defined like this:

public enum OriginLocation {TopLeft, BottomLeft};

public class Direction {
    public static OriginLocation Origin;
}

This would make the name less confusing and better reflect what it does.
