<p>
Informs Pango that the way that the rendering is done
for <em class="parameter"><code>part</code></em> has changed in a way that would prevent multiple
pieces being joined together into one drawing call. For
instance, if a subclass of <a href="PangoRenderer.html" title="PangoRenderer"><span class="type">PangoRenderer</span></a> was to add a stipple
option for drawing underlines, it needs to call
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
pango_renderer_part_changed (render, PANGO_RENDER_PART_UNDERLINE);
</pre></div>
<p>
</p>
<p>
When the stipple changes or underlines with different stipples
might be joined together. Pango automatically calls this for
changes to colors. (See <a href="PangoRenderer.html#pango-renderer-set-color"><code class="function">pango_renderer_set_color()</code></a>)</p>
