new Bach fugue visualization with ly2video!

[Adam Spiers]

Hi all,

ly2video, my adopted child, has grown up fast without me noticing :)
Very excited to say I got a wonderful email earlier from the clever
folks at algomus.fr notifying me that they have significantly improved
ly2video, and providing an example of what they've taught it:

Here's the pull request they've sent me, and it looks extremely good
at first glance - I'm looking forward to reviewing!

Enjoy!
