The intersection between different rectangles has been
achieved by stacking them on top of each other and decreasing and
increasing the top and bottom offset accordingly to the rectangle
keeping the left and the right offset intact which in turn coalesced
them to each other helping in achieving multiple intersecting rectangles.
The desired color fill pattern is then achieved by setting the fill
color which in turn would fill the shape with the provided color
in accordance to the even-odd filling rule.
