As soon as we ripple drag the selected region out of the original track,
::remove_unselected_from_views() is called and the rippled regions on the
original track are not covered when ::remove_selected_from_views() is called
again in ::finished(). Therefore we need to shift the regions remaining on the
original track back and forth again, in order to have them properly in the undo
history.

This is work in progress towards fixing stacked region's region-gain
and multiple discontinuous regions spanning multiple tracks.
AutomationRangeDrag::setup() still does not collect all AutomationLine
points for certain overlap scenarios. There's more to come...
Separate Snap from Grid. Lots of naming changes.
Multiple simultaneous snap options allowed. Grid is one of the possible Snap options.
Grid uses the same data as the rulers. Replace complicated tempo_lines with simple grid_lines.
The Grid is zoom-scale-sensitive along with the rulers. If you are zoomed out, grid becomes coarser.
Snapped Cursor is a line that follows the edit point, and indicates where the operation will occur.
This replaces and extends the line that appears with the Cut tool.
New associated preferences: snap_threshold and show_snap_cursor.

and video in order to keep the legible
It was assumed that the drag takes place within an area of musical time.
This is not true for the space before any non-initial
meter-locked tempo.
In the case of the initial tempo, there is no previous section
to perform an end-drag on.
If we've clicked on a tempo bar before the initial tempo,
don't allow anything to happen.
If it was just a click, ensure the tempo curve colour is restored.
* If the use-time-rulers-to-zoom option is enabled, -all- cursor drags can zoom.
* Behavior has been tweaked so it is easy to scroll without zooming, if you want to.
- a tempo marker may now be set to always continue (clamped)
this means that the end tempo of the previous section will
track the start tempo during tempo ops.
it mimics the behaviour in 5.8, with the gui indicating
the curves to be changed.
most changes are due to a new design where tempo discontinuities at the
beginning of a ramped section may be set.
this allows easier mapping of live performance, especially in
the common case of a ramped ritard before the beginning of a new section.
feature summary:
holding constraint modifier (shift) while dragging the BBT ruler area
drags the tempo lines by changing the start tempo (as before)
holding copy modifier (control) while dragging the BBT ruler area
drags the tempo lines by changing the end tempo (ahem. not quite there)
dragging a tempo mark while holding constraint (shift) will change the
previous end tempo to match the marker position *worth trying*.
holding constraint and copy modifier (control + shift) while dragging
the BBT ruler area attempts to'pinch' or twist the surrounding tempi
sp that later ones are not repositioned (currently suffereng from
rounding errors)
- wysiwyg (during drag) when dragging more than one note across
a tempo change.
- introduces a muscal equivalent of snap_delta (only used for
note drags atm)
- split earliest note in selection into a separate function
- MRV::copy_selection() returns the equivalent _primary note
to avoid offset hell.
- RV::snap_frame_to_frame returns a MusicFrame
- prevent note drag moving before region start.
snap now fills in a struct (MusicFrame) which contins a snapped frame
along with a music divisor.
this gives useful information wrt magnetic snap which may or may not
have rounded to an exact musical position.
region position may now be set musically (using quarter notes for now).
this patch fixes several problems in the current code:
- dragging a list of music-locked regions now maintains correct
musical offsets within the list.
- splitting regions using magnetic snap works correctly (#7192)
- cut drag should now work correctly with magnetic snap.
- musical length of split midi regions is no longer frame based.
If a track is selected during the drag (by moving the mouse pointer into a new track), but it was not
selected at the start, and is then de-selected (by moving the mouse back out of it), then remove
it from the selection.
This is a common operation used for zooming in other DAWs like Ableton Live and
Cubase. To support such a usage pattern without changing the existing behaviour
of the ruler area I've made it an option that is false by default.
The behaviour of RulerDragZoom is intentionally different than a CursorDrag
that occurs in the rest of the ruler area in that it doesn't follow the snap to
grid setting and no locate related stuff occurs until button release.
There are some issues with responsiveness with more than a few hundred regions
or a large amount of MIDI events/notes.
Implements feature #6768
- use exact beats to determine frame position.
- see comments in tempo.cc for more.
- this hasn't been done for split yet, but dragging and
trimming are supported.
- add_midi_region used to commit, resulting in
_region->set_position() adding a command when there was
no current transaction. The sub-bug here was that repeatedly
calling set_position() on the new region resulted in nonsensical
automation movement after the drag.
