	LXVEC(ix1.i2.r, iy1.i2.r, ix2.i2.r, iy2.i2.r [,kolor.i1.r])

	This routine will draw a vector from (IX1,IY1) to (IX2,IY2) on the
	LX color graphics display window.  Vector color is determined by the
	optional color code argument KOLOR.  See the descriptions of the LXPNT
	and LXMODE routines for information on color codes.  Vector width is
	determined by the most recent call to LXVWID.  Vector pattern is
	determined by the most recent call to LXPATT.
