                     21: compares two Points
                     22: and returns
                     23: a 1 if the Points are equal or a 0 if they are unequal.
                     24: Two Points
                     25: are equal if the corresponding coordinates

                     33: function
                     34: compares two Rectangles
                     35: and returns
                     36: a 1 if the Rectangles are equal or a 0 if they are unequal.
                     37: Two Rectangles
                     38: are equal if all four corresponding coordinates are equal.
