Set relative margin width, aspect ratio, and relative
justification that define current device-space window. If you want to just use the previous value for any of
these, just pass in the magic value PL_NOTSET. It is unlikely that one
should ever need to change the aspect ratio but it's in there for
completeness.
If <a class="link" href="plsdidev.html" title="plsdidev: Set parameters that define current device-space window"><code class="function">plsdidev</code></a> is not called the default values
of <code class="literal"><em class="parameter"><code>mar</code></em></code>,
<code class="literal"><em class="parameter"><code>jx</code></em></code>, and
<code class="literal"><em class="parameter"><code>jy</code></em></code>
are all 0. <code class="literal"><em class="parameter"><code>aspect</code></em></code>
is set to a device-specific value.
