<p>A <a class="link" href="GcrRenderer.html" title="GcrRenderer"><span class="type">GcrRenderer</span></a> is an interface that's implemented by renderers which wish
to render data to a <a class="link" href="GcrViewer.html" title="GcrViewer"><span class="type">GcrViewer</span></a>.</p>
<p>The interaction between <a class="link" href="GcrRenderer.html" title="GcrRenderer"><span class="type">GcrRenderer</span></a> and <a class="link" href="GcrViewer.html" title="GcrViewer"><span class="type">GcrViewer</span></a> is not stable yet, and
so new renderers cannot be implemented outside the Gcr library at this time.</p>
<p>To lookup a renderer for a given set of attributes, use the <a class="link" href="GcrRenderer.html#gcr-renderer-create" title="gcr_renderer_create ()"><code class="function">gcr_renderer_create()</code></a>
function. This will create and initialize a renderer that's capable of viewing
the data in those attributes.</p>
