viz takes too long to start up

[Robert Collins]

bzr viz takes several seconds to come up on a bzr branch, which is
rather long. Bringing up an empty window quickly, and then populating it
would feel much nicer to the user I think.

With the new graph code, it should be possible to iterate over the
ancestors as we need them.

The only thing this does is show the window before filling in the graph.
This doesn't help much as you still have to wait - you're just staring
at an empty window instead of no window at all.

It should be possible to gradually draw the graph starting with the tip
revision without the long wait, so I don't think this bug is fixed yet.

Well merge sorted is not yet redesigned to allow incremental sorts with

Showing the window upfront is a massive improvement IMO and fixes the
key startup problem - that of users starting it multiple times.

I asked Gary to implement an indicator similar to the one that Revision Browser has, so the user can see on the UI, that it's working currently. That one should cause even less confusion...

I have basically rewritten the graph code, including a change to load the revision data incrementaly, improving the time it takes to display the first screen of data by 82%. Please see the vizchanges branch linked above.
