Yes, this is something I started and obviously did not finish. If 
finished, it would be a useful addition to the User's guide. And now 
while looking at that, I see some errors in the Image Tutorial...

This was a draft framework for filling out the User's guide. A push was 
started a couple summers ago, progress was made, but major chunks (some 
of which I signed up for) are still missing.

+1 
I guess I always find the docs for those using the search, but
it'd be better to have them at least somewhat integrated with the
rest of the docs. Plus it will bring the zeroth Betti number down
for the docs, and I'd consider it a bug if that number is
anything other than 1.

Virgil,
Thanks for noticing this. There are several missing methods in the various
3D collections and artists, and I am sure we haven't found them all yet. I
am currently too busy to investigate why this particular one was missing,
but in about a month I will have some time to do so.

Yes. I think we should add a toolkit category to the table of contents 
and add this and AxesGrid there.

For mpl_toolkits/mplot3d/index.rst, I cleaned it up and improved it
slightly, but I have no clue where in the broader documentation it belongs.
Maybe we need an entry for mpl_toolkit items?

We have a few orphaned RST pages in the documentation tree -- these are 
files that are in our source tree, but are not linked to by any table of 
contents within the documentation.
It's possible that some of these were started but not completed, or 
obsoleted but not fully removed. I've looked up the last few authors of 
each file -- can you help me triage them?
