Sets the area fill pattern. The pattern consists of 1 or 2 sets of
parallel lines with specified inclinations and spacings. The
arguments to this routine are the number of sets to use (1 or 2)
followed by two pointers to integer arrays (of 1 or 2 elements)
specifying the inclinations in tenths of a degree and the spacing in
micrometers. (also see <a class="link" href="plpsty.html" title="plpsty: Select area fill pattern"><code class="function">plpsty</code></a>)
