The StraightEdgeRecord stores the edge as an X-Y delta. The delta is added to the current drawing position, and this becomes the new drawing position. The edge is rendered between the old and new drawing positions. Straight edge records support three types of lines: 1. General lines. 2. Horizontal lines. 3. Vertical lines.
