View Ref-FileBOUNDARY n

n: iexp

The command BOUNDARY uses the Function vsf_perimeter() to switch off (or on)
the border normally drawn round a filled shape (with PBOX, PCIRCLE, etc). When
n is not zero, a border is drawn around the filled area, when it is zero, no
border is drawn.

Example:

    DEFFILL 1,2,2
    BOUNDARY 1          !switch on border
    PBOX 50,50,100,100
    BOUNDARY 0          !swith off border
    PBOX 150,50,200,100

--> Draws two filled rectangles, one with and one without a border.

    Internally calls vsf_perimeter().
