This command takes as input two ordered pairs (x

1

,y

1

) (x

2

, y

2

), or two pairs of 

pixel coordinates {#n

1

 #m

1

} {#n

2

 #m

2

}.  It draws the box whose diagonals are 

represented by the two pairs of coordinates in the input.

This command is used to draw an arc.  ARC takes as input the following 
objects:

Θ Coordinates of the center of the arc as (x,y) in user coordinates or {#n, #m}

in pixels.

Θ Radius of arc as r (user coordinates) or #k (pixels).
Θ Initial angle θ

1

 and final angle 

θ

2

.

These functions take as input the coordinates of point in user coordinates, (x,y), 
or in pixels {#n, #m}.
