Log Message:
-----------
Use a custom encoding containing all of the used glyphs when writing out a Postscript Type 3 font. This resolves a bug when converting Ps output containing non-standard characters (such as the minus sign) to Pdf using ps2pdf/gs 8.7 or later.

Changes beyond 0.99.x
=====================
+* The :class:'~matplotlib.collections.EllipseCollection' has been
+ changed in two ways:
+
+ + There is a new *units* option, 'xy', that scales the ellipse with
+ the data units. This matches the :class:'~matplotlib.patches.Ellipse`
+ scaling.
+
+ + The *height* and *width* kwargs have been changed to specify
+ the height and width, again for consistency with
+ :class:'~matplotlib.patches.Ellipse`, and to better match
+ their names; previously they specified the half-height and
+ half-width.
+
* There is a new rc parameter ``axes.color_cycle``, and the color
cycle is now independent of the rc parameter ``lines.color``.
:func:`matplotlib.Axes.set_default_color_cycle` is deprecated.
