From 1bba73950fa01cee6bf534730926c33992eca588 2011-01-24 05:29:41
From: Brian Granger <ellisonbg@gmail.com>
Date: 2011-01-24 05:29:41
Subject: [PATCH] Lots of work on the display system, focused on pylab stuff.

* Moved the pprint attribute to PlainTextFormatter.
* Added DisplayFormatter.plain_text_only for disabling all but the
  plain text formatting. This is now used by doctest_mode.
* Remove result_display hook.
* Fixed doctest_mode magic.
* Refactored inline matplotlib backend to use new display system.
* Added display formatter for matplotlib.figure.Figure objects.
  so the display system will show the svg for them.
* Added display and display_png to the user's namespace in pylab.
* Cleaned up pylabtools.py
