I committed the last few months work on tempos & swing to the branch
big-tuplet-rewrite. There are many things to be said about that code, but
since my comments about coding tend to be tl;dr, I'll sum up the main
things briefly:
* Most important, this all lives on branch big-tuplet-rewrite and
will stay there until it's proven stable.
* It can swing via tempos. Had a devil of a time getting the timings
perfect - they were within 2% pretty early, but took several
redesigns to get them perfect. Now they are accurate to within
display precision.
* Briefly, it transforms a range of tempos to Hermite cubic splines,
operates on that, converts it back. Lots of technical stuff.
* New classes, especially TempoChange and HermiteTempoChange. Pulled
a lot of Composition code into TempoChange and TempoChangeInSitu.
* This was way too slow, so I wrote CompositionTimeMutator and mostly
operate thru it, and that's much faster.
* PasteConductorData, PasteRangeCommand, DeleteRangeCommand messed
swing up, but I rewrote them to be hopefully more robust. I'll try
to document that.
* I did not yet do as Tim Munro suggested with an assortment of
tempo-operation commands, but that should be easy now (which is a
phrase that always comes back to haunt you, but I haven't learned
yet). I intend to add them, but I thought it best to commit now
that it's semi-stable.
* By the end I had made or enlarged so many classes in base/ that it
was getting messy, so I thought it best to make new directories for
them:
* base/eventhelpers - Classes that would have gone in NotationTypes.
TimeSignature moved there too.
* base/selections - Classes that were in Selection.h
* Wrote some convenience stuff that I'll try to document.
