ANN: matplotlib-0.71

This matplotlib release will be included in enthought's next release
of enthought python, which is widely used by windows users for
scientific computing. I'd like to get an stable-as-possible release
in, since enthought python is released very infrequently. Joe Cooper,
who is handling the release, says we can get fixes in until sometime
on Monday, so I'd be much obliged if you all could stress test this
release in case I need to get a bug-fix in. There have been some
potentially script breaking substantial changes to the numerix module
described below, so these tests are doubly important.

What's new in matplotlib 0.71

numerix refactor

  The organization of the numerix module was refactored to be mindful
  of namespaces. See pylab no
  longer overrides the built-ins min, max, and sum, and provides amin,
  amax and asum as the numerix/mlab versions of these. pylab defines
  __all__ to prevent surprises when doing from pylab import *. To see
  the complete list of symbols provided

    >>> import matplotlib.pylab
    >>> matplotlib.pylab.__all__

contour zigzag bug fixed

  Thanks Nadia for the blood, sweat and tears, and Dominique for the

contour colormaps

  Contour now uses the current colormap if colors is not provided, and
  works with colorbars. See examples/

colorbar enhancements

  Horizontal colorbars supported with keyword arg
  orientation='horizontal' and colorbars can be placed in an arbitrary
  axes with keyword arg cax.

accents in mathtext

  Added accents to mathtext: \hat, reve, \grave, ar, cute, ilde, ec,
  \dot, \ddot. All of them have the same syntax, eg to make an overbar
  you do ar{o} or to make an o umlaut you do \ddot{o}. The shortcuts
  are also provided, eg: "o 'e \`e \~n \.x \^y . See

fixed super/subscript parsing in mathtext

  Widowed superscripts now work, eg r'$^12 m{CO}$'

little bugs and enhancements

  Plugged some memory leaks in wx and image module, fixed x,y args in
  contour, added latex symbol kappa, fixed a yticklabel problem under
  change in clim, fixed colorbar number of color bug, fixed
  set_clip_on bug, reverted pythoninspect in tkagg, fixed event
  handling bugs, fixed matlab-compatible load function, exposed vbox
  attr in FigureManagerGTK.

I did not get a chance to get the aspect=preserve imshow bugs fixed on
this iteration. Something for next time!
