* Don't need TrackFactory to make LabelTrack
* Don't need TrackFactory to make NoteTrack
* Don't need TrackFactory to make TimeTrack, or ZoomInfo in the factory
* Remove some forward declarations
* Rename TrackFactory as WaveTrackFactory, move it out of Track.cpp
... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
This is now the behavior of Zoom Reset, with Max Zoom being given the previous behavior. Shift+Right-Click alternates between the two -- it zooms to all notes, unless it currently is zoomed to all notes in which case it performs a max zoom.
This fixes Bug 2093. It also fixes Bug 1815, by performing the all-notes zoom when importing a track.
This simplifies a bunch of other work -- in particular zooming so that specific notes are visible, and keeping the same notes on screen when resizing the track.
Also included is a fix to YToIPitch to make it use mPitchHeight directly -- this solves some roundoff errors, which previously caused inaccurate results on some zoom levels.
... for wxString and wxArrayStringEx, holding file paths (absolute or relative,
directory or plain file); to be replaced later with different types
(not yet using std::vector, becase of some uses of wxArrayString::Index with
two arguments)
Simplify the logic of duplication of NoteTrack. Duplicates are always in
serialized state. Un-serialization can happen on demand in any of the
NoteTrack operations that require a defined sequence.
Changing the duration of the sequence after paste is needed,
as it was also needed, when I fixed Stretch at commit
90eb4ec142. I don't know if this should be
considered a bug in Allegro that we are compensating.
* Fix memory leaks.
* Add comments about initializations and checking for successful results.
* Add checks for NULL deref.
* Consistency in "TODO" vs "TO-DO" comments!
