matplotlib Code

Fix Postscript graphics context bug (Thanks Paul Novak for finding this)

Raise ValueError if legend is called with invalid numpoints (Paul Novak)

Add AxesImage.interpnames (based on old request by fredmfp@...)

Fixed right-hand y tick label positioning bug reported by Darren Dale

Modified BoundaryNorm, examples, colorbar support

Force the pdf backend to always use 72 as the dpi value. This fixes
the size problem of the resulting files (since the size is measured in
units of 1/72 inch). TODO: the user now has no control over the dpi
of images.

added manual axis example

Fixed bug in vlines: it was not expanding scalar ymin, ymax

Added BoundaryNorm to support irregular discrete color intervals

Fix tick-alignment problem (Thanks Jörgen Stenarson)
