If <em class="parameter"><code>patt</code></em> is zero or less use either a
hardware solid fill if the drivers have that capability (virtually all do) or
fall back to a software emulation of a solid fill using the
eighth area line fill pattern. If 0 < <em class="parameter"><code>patt</code></em> ≤ 8, then
select one of eight predefined area line fill patterns to use (see
<a class="link" href="plpat.html" title="plpat: Set area line fill pattern"><code class="function">plpat</code></a> if you desire other patterns).

The desired pattern index. If <em class="parameter"><code>patt</code></em>
is zero or less, then a solid fill is (normally, see qualifiers above)
used. For <em class="parameter"><code>patt</code></em> in the range from 1 to 8 and
assuming the driver has not supplied line fill capability itself (most
deliberately do not so that line fill patterns look identical for
those drivers), the patterns consist of (1) horizontal lines, (2)
vertical lines, (3) lines at 45 degrees, (4) lines at -45 degrees, (5)
lines at 30 degrees, (6) lines at -30 degrees, (7) both vertical and
horizontal lines, and (8) lines at both 45 degrees and -45 degrees.
