Looks good! I don't think you missed anything. Just be sure to get the
behavior right regarding the copying vs. referencing of clips...
I think this is a good model: (from another mail)

* dragging a clip from the clipmgr into a track creates a reference to
it there (not a copy).

* modifying a clip with multiple references creates a copy before the
modification, so that a new clip is created. (the new clip will have
references=1)

* modifying a clip with only one reference (the one you're editing)
changes the clip, no copy is made, so no additional clip is created.

* dragging an audiosource from the clipmgr creates a new clip of the
whole file.
