<p><strong>Note for backend implementers:</strong></p>
<p>When you are trying to determine if you have gotten your bounding box
right (which is what enables the text layout/alignment to work
properly), it helps to change the line in text.py:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">if</span> <span class="mi">0</span><span class="p">:</span> <span class="n">bbox_artist</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">renderer</span><span class="p">)</span>
</pre></div>
</div>
<p>to if 1, and then the actual bounding box will be plotted along with
your text.</p>
