[PATCH] Clusters

[Juergen Reuter]

Hi!

Here is a patch that implements clusters (and fixes various minor bugs).
Have fun!

Some notes:

* Parsing currently seems to be very fragile.  I had severe problems
  to create an example file that does not cause a parser error.

* At a first try, I patched the parser to accept a "\startCluster" and
  "\stopCluster" command to create span requests.  This worked well.
  Then, for protocol reasons, I removed this code and used
  #(make-span-event ...) instead to create span requests.  This still
  works, but the start and end point of the spanner are shifted;
  e.g., if I say "... c d #(make-span-event 'ClusterEvent STOP) e f
  g a b", the request refers to the "a" or "b".  This is especially
  true, if polyphony like "<c d>" occurs shortly beforehand.

* The moulding blotdiameter model (for explanation, see comments in
  Lookup::round_filled_polygon()) led to a very hacky polygon
  implementation, that is not even well-defined.  Just for the record:
  I still vote for the additive model.

Greetings,
Juergen
