The same information you see in the TSVN log dialog:

* changed paths

The log for an item only shows those revisions that path got directly
changed. But then the information is missing when that item got
moved/renamed/copied due to a move/rename/copy operation on a parent
item. And the revision graph needs that information.
You can try it yourself: show the log for your /trunk folder. You won't
see any information about copies of /trunk to e.g. /tags/version-XXX.
Those log entries are missing because it didn't affect /trunk directly -
the /trunk folder (or an item below it) wasn't modified.
That's why we need to get the log from the repository root.

Most people don't have files in the repository root. At least not if you
follow the recommended folder layout.
But if you revoke the read access to some subfolders, then the revision
graph won't show you copies from those because the log won't show them.
Which shouldn't be a problem really, but just so you know that the
revision graph won't show those and you won't expect it to do that.

When I started the revision graph, I knew that this would be an issue
which I simply can't solve. But it was either that, or no revision graph
