I would have loved to split this apart, but there are just so many interrelated changes,
it makes little sense and would be a huge effort that would break future git bisect
use because so many intermediate commits would not compile
Remove the is_xrun parameter from Editor::mouse_add_new_marker(), and just
create the marker directly in ARDOUR_UI::create_xrun_marker(), so that xrun
markers don't become automatically selected when they appear.
Achieve this by adding a new hscroll group just for cursors.
That requires a slightly smarter window_to_canvas() to deal with overlapping
sensitive scroll groups. New rule is that scroll groups can overlap, but the
most sensitive one found from the top down will be chosen to translate
coordinates. This basically means don't overlap scroll groups with different
sensitivities.
In the presence of scroll groups, having a canvas-wide window_to_canvas()
and/or canvas_to_window() fundamentally makes no sense. At some point in the
glorious future we should kill those and use only item-relative coordinate
translation.
Fix several other cases where a single mouse click could cause several
(not nested) selection ops.
Fix missing selection memento for midi notes and midi commands.
Rename some variables.
Fix random style issues.
Idea here is for importing large multi-track MIDI files to be immediately
listenable upon play without tediously adding a ton of instrument plugins
manually.
combines selection related editor properties with the current editor selection.
The related editor properties are:
mouse mode,
zoom setting,
left frame of the canvas,
y origin of the canvas.
Selection state now includes region views (storing the underlying region id)
and time.
This patch also fixes a region mute undo bug.
No functional changes in this one (for easier auditing), but towards having
round up/down only if necessary modes, rather than kludging around that
situation with a double round as we do currently.
The idea here is that pasting several times to the same location doesn't make
sense. Instead, the paste is appended past the last paste, snapped to the
grid. This make it simple to replicate a given section a number of times,
simply by copying once and pasting several times.
This behaviour only appears when successive pastes are done to the same
location (whatever the edit point is). When the paste point changes, the
"multi-paste" state is reset.
