2012-11-27 Added the *mtext* parameter for supplying matplotlib.text.Text
2+
instances to RendererBase.draw_tex and RendererBase.draw_text.
3+
This allows backends to utilize additional text attributes, like
4+
the alignment of text elements. - pwuertz

2012-11-16 plt.set_cmap no longer throws errors if there is not already
27
an active colorable artist, such as an image, and just sets
38
up the colormap to use from that point forward. - PI
