[matplotlib-devel] reimplemented legend class

[Jae-Joon L. <lee...@gm...>]

Hello,

I have been working on reimplementation of the legend class, and I
guess it is mostly done. The biggest change is how each items are
placed. For this, I made a simple container class("offsetbox.py"),
which can pack the mpl artists in a similar way as widget packing in
gtk, tk, etc.

 * paddings are given as fraction of the font size.
 * baseline alignment (when supported by backend)
 * multicolumn
 * expand-mode (see the last panel in the attached figure)
 * fancybox for the frame


It should be backward compatible. The backend_driver.py runs fine and
all the examples I checked looks good.
So, here is the patch and example figure. It would be great if others
review and test this patch.

Regards,
