plfill3: Area fill in 3D 

DESCRIPTION:

	Fills the 3D polygon defined by the n points in the x, y, and z arrays
	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, y, and z then plfill3
	will fill in between them. 

SYNOPSIS:

plfill3(n, x, y, z)

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. 

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