Comment(by mpatel):
A quick (and crude) change to `Graphics.save()` sets up a
`background_color` option:
{{{
#!python
if savenow:
[...]
background_color = None
if kwds.has_key('background_color'):
background_color = kwds.pop('background_color', False)
figure=self.matplotlib(*args, **kwds)
[...]
if background_color:
figure.patch.set_color(background_color)
for ax in figure.axes:
ax.patch.set_color(background_color)
# Not sure how to avoid using these:
options['edgecolor'] = background_color
options['facecolor'] = background_color
figure.savefig(filename,dpi=dpi,bbox_inches='tight',**options)
}}}
If we can avoid using the `savefig()` options, perhaps we can set a
background color ''and'' transparency level entirely in `matplotlib()`.
Then, I think, we could handle combinations like
* `transparent=True, opacity=0.5`
* `opacity=0.8, background_color='#ffbefa'`
in a way a user expects. Thoughts?
