Decide on best-of-breed future approach to .ly video generation

In addition to ly2video, there are at least two alternative approaches to generating video from LilyPond files:

• mkvideo
• An approach by Thomas Tensi announced on lilypond-user and explained in detail on his blog

All three have their pros and cons. Ideally the community should get together and figure out a way forward which provides a single best-of-breed tool, since the community is too small to be able to afford to needless fragment and duplicate effort. If that means ditching ly2video altogether, so be it. Suggested steps:

• Document high- and mid-level summaries of the approaches made by all three. For example, "ly2video essentially generates an extremely wide and low single-system png of the score, and then crops that at different places to generate video frames which are then synchronised with playback" would be the high-level summary, but then the mid-level summary would go into more detail about how it figures out the exact placement and playback timing of each grob.
• Compile a matrix of the advantages of each.
• Discuss as a community and figure out the best way forward.
