... The return codes were mostly ignored anyway, and exceptions will be thrown
instead.
It seems there was also confusion whether the return values of Track::Paste
and Track::SyncLockAdjust were to indicate success or indicate whether there
was any change. No matter now.
A sync-lock group is a maximal sub-sequence of the tracks, containing:
one or more wave tracks (and/or Note tracks, if MIDI is enabled),
and zero or more label tracks.
(These are not exhaustive of all of the types of tracks.)
So redefine Next(), Prev(), and Last() carefully to implement this intention.
... And in some places where a library uses signed types, assert that
the reported number is not negative.
What led me to this, is that there are many places where a size_t value for
an allocation is the product of a number of channels and some other number.

Don't make strange undo history if, e.g., R to record (or other keystroke
with undoable effects) interrupts a drag with undoable effects (like time
shift). Ensure that by first simulating a mouse button up event to stop the
drag, before dispatching the keystroke.
Don't crash if certain other drags, that do not have undoable effects, such
as selection or vertical ruler drag -- are interrupted by a keystroke
command (Ctrl+C in particular could cause crash). However, in these cases,
the drag is still allowed to continue.
In addition, the Xcode project can now build against the 10.6
or 10.7 SDKs. All that is needed is to change the SDK version
and the other settings will change automatically.
New project. New track. Generate sound -- do not cancel. Select all,
generate sound again -- this time, do cancel the progress dialog.
Undo, so you see one, empty track again. Save. Close. Reopen.
The cause of these orphans is different from the first case. The previous
commit is necessary but not sufficient to fix this.
EXPERIMENTAL_LINKING -> EXPERIMENTAL_SYNC_LOCK
Restore some "border" lines in TrackInfo.
Get rid of unused DEFINE_COLOUR( clrTrackInfoSyncLockSel...).
Clean out some undocumented commented-out code. Add/remove some comments.
