I've now done these steps. With a lot of tedious work so that all the
merges were preserved as accurately as possible

The result can be seen:

Please take a look and see if it looks good.

Some notes:

 - The final commit is a merge of gnome-2-26 branch. It was a
   straightforward merge but I haven't actually tested it.
   Everything else is literally identical to what was in
   the metacity-clutter repository.

   I decided to merge gnome-2-26 rather than head, since it seemed
   like a better place to diverge - I didn't want to pick up half
   finished changes just being started on the gnome-2-27 line.

 - All the rebased commits have:

committer Owen W. Taylor <otaylor fishsoup net> 2009-04-08 19:16:50
   Instead of the committer and commit date of the original. The
   author and author dates are fine.

   The main downside of this is that the dates appear wrong in cgit.
   It's not too easy to fix ... one easy thing I could do is make the
   committer and commit date equal to the author and author date
   for everything. Which would be less strictly accurate than the
   current version, but less jarring as well.

 - I deleted all Metacity branches other than a single master branch

 - I deleted all Metacity tags not on the master branch

 - I deleted some tags from the metacity-clutter repository that didn't
   seem needed. clutter-0-9-pre-merge or whatever.

 - I carried over the release-2.25.144_0.1, etc, tags. They are now
   annotated tags rather than signed tags since I couldn't sign
   the rewritten commits as Tomas ;-)

These are mostly still to be done.
