This also adds interaction with sections in the
Arrangement Ruler.
Note that selecting a range switches to the Range tool.
This is enforced because time-range selection is only meaningful
with tools that perform edit operations on the whole timeline.
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.
During drag-motion callbacks the data to be dragged is n/a.
However we like to discriminate if drop is possible.
When dragging regions, the data-type of the region to be dragged
is unknown, so different `x-ardour/region` targets are not an
option, either.
Until a better option is presented, a static global is used
to set the data-type for region.pbdid drags.
This is in preparation for allowing to drag trigger-regions
or trigger-slots. Those will not use a static singleton
PublicEditor API.
Additionally this constrains Ardour-internal drags to Ardour
(via Gtk::TARGET_SAME_APP).
Unconditionally use the mouse-cursor as zoom-focus when holding
<ctrl> while scrolling on the canvas.
This is consistent with using ctrl + scroll in the ruler area.
When Prefs > Editor > Zoom to mouse position... is disabled.
Ctrl + Scroll now allows to override the current zoom-focus,
and zoom in/out at the mouse-cursor position.
The drag code expects coordinates in canvas coordinates, but we were not translating them at the editor level (canvas event handling
does do this, but cannot affect the situation if the event falls through to the editor)
Copyright-holder and year information is extracted from git log.
git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
This preserves the stereo-ness of files that were imported or recorded in stereo.
ToDo (maybe someday): provide a disclosure triangle that exposes the individual channels in a multichannel region
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible
* 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.
GTK events are still handled while un/loading a session (e.g display
"Loading" message or showing the splash triggers an event-loop run).
Global canvas elements (e.g. Rulers) may respond to session-specific
actions.
