plfill: Area fill 

DESCRIPTION:

	Fills the polygon defined by the n points (
	x[i], 
	y[i]) using the pattern defined by plpsty or plpat.  The routine will
	automatically close the polygon between the last and first vertices. 
	If multiple closed polygons are passed in x and y then plfill will
	fill in between them. 

SYNOPSIS:

plfill(n, x, y)

ARGUMENTS:

    n (PLINT, input) :      Number of vertices in polygon. 

    x (PLFLT *, input) :    Pointer to array with x coordinates of
        vertices. 

    y (PLFLT *, input) :    Pointer to array with y coordinates of
        vertices.
