VelocityGhostRegion used the visibility of the "parent" note canvas item of a
lollipop canvas item to determine the lolli's visibility. But during the
construction of the MidiRegionView, the note's container is not yet visible, so
this fails.
In addition this logic would hide lollis for notes that are outside the current
visible note range of the track (because the parent note item was not visible).
This change adds a method to MidiRegionView to decide if a note is within the
region's time range, and if so, we show the lollipop item. This means that
lollis for notes outside the note-range will still be visible, which seems more
correct. In addition, the nascent condition of the parent note's container no
longer affects lolli visibility.
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.
In the presence of tempo-changes distinguishing between offsets and
absolute positions is signficant. It is only valid to convert absolute
times using the tempo-map
Furthermore since GUI zoom-factor is time-invariant (samples per pixel),
all GUI operations must explictly use samples (or timecnt). It is not
valid (and problematic) to use use a location dependent timepos.
these functions operate on the _note_diff_command,
which is explicitly a NoteDiff, not a generic DiffCommand
also fix a few thinkos where the ambiguous naming led to errors
::model_changed() is used when the model has changed (eg. new notes or some
notes deleted); ::view_changed() is used when only some view parameter (e.g.
zoom, scroll, track height etc) has been altered.
Not fully functional yet (::view_chanted() ignores scroll)
When adding a note, use these criteria to choose the channel number:
* if the user has explicitly specified a note in the pulldown, use that
* if the user has AUTO selected and we are in a region, choose the nearest note's channel (consistent with velocity behavior)
* as a fallback, query the track for its channel-filter (old behavior)
This adds a few exceptions to the general preference
"Sound MIDI notes as they are being selected in the editor".
* Select all no longer plays _all_ notes.
* Remain silent when selection is inverted or a range is selected.
* Play no sound when a saved selection is restored on session load.
1. Alt is still handled to change drag behavior
2. Selection doesn't store notes unless they are part of the cut buffer, which means we should not
be altering the note selection in the editor's selection object most of the time.
