<p>FreeType doesn't allow fonts to get smaller than 1 pt, so all Agg
backends were silently rounding up to 1 pt. PDF (other vector
backends?) were letting us write fonts that were less than 1 pt, but
they could not be placed properly because position information comes from
FreeType. This change makes it so no backends can use fonts smaller than
1 pt, consistent with FreeType and ensuring more consistent results across
backends.</p>

<p><code class="xref py py-obj docutils literal notranslate"><span class="pre">matplotlib.Figure.legend</span></code> used to check if a line had the

<p>Adding an axes instance to a figure by using the same arguments as for
a previous axes instance currently reuses the earlier instance. This
behavior has been deprecated in Matplotlib 2.1. In a future version, a
<em>new</em> instance will always be created and returned. Meanwhile, in such
