different PNG and PDF output...

Hi,

with the new version of matplotlib, the legend looks different in png and
pdf!

I could post examples, but you can look in the galery also:
http://matplotlib.sourceforge.net/gallery.html

for example the legend_demo3
http://matplotlib.sourceforge.net/examples/pylab_examples/legend_demo3.html
* PNG:
http://matplotlib.sourceforge.net/_static/plot_directive/mpl_examples/pylab_examples/legend_demo3.hires.png
* PDF:
http://matplotlib.sourceforge.net/_static/plot_directive/mpl_examples/pylab_examples/legend_demo3.pdf

You see in the png the lines are short and not vertically centered, padding
between axes an legend text are ignored .. and so on

This looks like a dpi issue -- that is the only difference between the regular and hi-res png. Jae-Joon -- do you have any thoughts? Perhaps something is dpi-dependent in the new legend code where it shouldn't be?

I also observed this with eps output. The png looked fine, but the eps legend
was very large in my case.

Hmm, it is not clear to me if this is a same issue. I think eps output
is not very sensitive to dpi thing in matplotlib.

I tried a few tests but couldn't see any obvious problems.
If my patch does not fix your problem, please report some more details.

OK, now it works! Thank you!

A little thing: the shadow of the legend box is not scaling with the dpi.
For example with 300 dpi I can't discover the shadow...

This also should be fixed in the maintenance branch and the trunk.
Thanks for reporting.
