the API now provides the option to call ::get_grid() with an iterator which may
be re-used on subsequent calls. This avoids unbounded O(N) "walks" from the
marker preceding the start point of the grid to the start point.
This commit also includes "fast-path" code for the common case of a single
tempo and single meter
Make click & drag in the left-hand half of a region with the Timestretch
tool stretch the region on its left, leaving the end position of the new
time-stretched region in the same place as the end of the original.
Deleting _track_canvas_viewport automatically destroys
any child Items. The LocationMarker's group was already destroyed
when ~ArdourMarker() runs and calls `delete group`.
So first delete the marker, then the canvas
* correctly handle clicks on the immediate right or left of a beat line
* prefer Mid-Twist and End-Stretch terminology over Twist and Linear
* static-tempo vs ramped-tempo is orthogonal to mid- and end- drags (TODO)
We now use the same actions in all modes, and the logic is:
1. is there a selected mixer strip and are we in it: if so, delete selected
processors
2. are we in draw or internal mode? if so ..
2a. if there are selected control points, delete them
2b. if not, attempt to delete MIDI notes
2c. done
3. continue with delete operation as before
When cutting multiple regions with Ripple-ALL, removing
the first region ripples the remaining tracks which includes
selected regions on those tracks which are to be cut later.
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.
This concept from 2007 is no longer required Temporal::get_grid
already limits the number of grid-lines depending on the step
size (mod-bar, beat_div) and start/end positions.
Import via Drag/Drop previously worked by selecting a track,
and then importing to the selected track.
This approach fails when the selected track is in a track-group,
and selecting the track also selects other tracks of different type.
Now the track to drop onto is passed directly passed through to
::finish_bringing_in_material as existing_track.
