This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
There already is a shaded coverage frame indicating
if a layer is audible. This leads to a more consistent view.
In addition changing layered mode now has to update the
colors (set_frame_color).
This fixes rendering of opaque MIDI regions (previously
MIDI regions were always transparent). This change provides a
way to "flatten" layered MIDI regions, while still allowing
to show the note-line and grid behind the regions.
This allows two reader threads to proceed without blocking each other, as can
happen when the butler renders a MIDI track into an RT-safe buffer while the
GUI reads the same MidiModel/Source for visual display.
This also requires a change in the type of reference held by
a MidiAutomationListBinder.
Both the MidiSource and MidiModel have a reference to each other, and it is
important that we avoid circular references to avoid problems with object
destruction. We had been accomplishing this by having the Model hold a
weak_ptr<MidiSource>. However, the lifetime of a MidiSource and its MidiModel
are coincident and there's really no need to use a smart ptr at all. A normal
reference is just fine. However, due to constructors that accept a serialized
state, we cannot use an actual reference (we cannot set the constructor in the
initializer list), so we use a bare ptr instead.
This forces a similar change in MidiAutomationListBinder, which also maintains
a reference to the Source. However, the only purpose of this object is to
ensure that if the Source is destroyed, relevant commands will be removed from
the undo/redo history, and so all that matters here is that the binder connects
to the Destroyed signal of the source, and arranges for its own destruction
when received.
Note that the previous construction of the binder, actually holding a
shared_ptr<MidiSource> would appear have prevented the Destroyed signal from
ever being emitted (from ~Destructible), and so this may also be a bug fix that
allows MidiSources to actually be deleted (the memory object, not the file).
This covers a race condition in session transport that when synced to an
external engine it sometimes occurs that at the end of ::realtime_stop()
::transport_stopped_or_stopping() returns false when ::setup_rec_box() is
called. In this case the rec boxes are not erased when the recoding transport
is stopped.
This fixes this behavior about the remaining rec boxes, however the race
condition remains.
The race condition is reported in #8104. It should be considered reverting this
commit once the race condition is fixed.

Previously only manual changes of the note-range using the scroomer.
The NoteRangeChanged() was ignored for implicit changes (e.g. while
recording, step-entry) and automatic-fit that didn't involve a drag
event.

Since 478f26b2ad, transport_rolling() is only true when actually rolling.
Count-in is a no-roll process (don't move playhead, no playhead UI
position interpolation 55b8b448).
But transport isn't exactly stopped either (preparing to roll), so
during count-in transport_stopped() == transport_rolling() == false.
Note lines on a MIDI-track were able to exceed the time-axis' height
towards the top. If a MIDI track was at the top, the TAV's canvas-group
would increase the overall bounding-box of the track-area and allow
tracks to visually bleed into the time markers group.
- for those not in the know, this series provides a way to
remove the temporal distortion introduced when using an
audio frame-based gui for music-locked objects.
In short, the gui uses an audio frame representation to move
objects. It displays the object using frame_at_beat(), quantizing
the time value to audio frames. This is fine until the user selects
that frame but expects it to be interpreted as a beat.
Thus beat_at_frame() would not produce the user-expected beat
(temporal quantization error of up to 0.5 audio samples).
This is one method of mapping audio time to music time accurately.
