I'm currently working on a patch to enable the matplotlib feature
shown in the video.  Notice that it's pure matplotlib, no change of
any plot parameters.  Unfortunately, or better to say fortunately? I
lost my changes by installing from svn, so I have to redo it, but this
times it's less hacky I believe.  I'm reworking colors.ColorConverter
completely but backwards compatible.

The second change applies to cm.ScalarMappable.to_rgba(), to use the
colors.colorConverter for applying the rc gray setting.

Then printing in grayscale will be possible for all features of
matplolib going one of this routes to get their colors, which should
be most.  Do you know any more?

To pursue on the ColorConverter class, it seems to me that this has
evolved organically, merging class attributes with module attributes.
Shouldn't this be fixed, by putting the class's methods into module
space?

Ben, I fully agree with you that figures should be able to be saved
both coloured and grayscale.  It was a misunderstanding.  What I meant
was, that it will not be necessary to display one part of the figure
in colour and the other in grayscale at the same time.
