LXFILL(mode.i1.r, ix.i2.r, iy.i2.r [,kolor.i1.r])
This routine draws filled polygons on the LX color graphics window
display. At least 3 verticies must be specified. If the polygon
is not is not convex, it may not be filled properly. Since the
polygon is broken down into triangles, if COMPLEMENT mode writing is
done, the interior edges of each triangle will be complemented twice,
leaving them unchanged. See the LXMODE description for information
on the various write modes.
MODE = 0 Defines the starting vertex and color of a new polygon. IX
IY are the starting vertex coordinates. KOLOR is the color
code with which the polygon is drawn. See the descriptions
of the LXPNT and LXMODE routines for information on how color
codes are used.
MODE = 1 Defines another vertex of the polygon. IX and IY are the
coordinates of the vertex. The KOLOR argument is not used.
