The ::start_drag() implementation now defers add/extend selection logic to
MidiRegionView::note_selected(), and drops the original limitation that we did
not do extend-selection on button press, only button release.
This commit leaves two issues outstanding:
1. unclear/ugly semantics for drag operations that reset the GUI thread's tempo map to the writable copy
2. undo/redo for the tempo map
These will be addressed in future commits
This was broken during development of ripple-all.
First explicit rdiff_and_add_command() was used, but
when that was reverted later, the original stateful_diff
was not restored.

This addresses an issue with missing guard points at the
beginning of a range drag when the range is not snapped to
a musical grid.
Note that the code below "same thing for the end" does not use
.beats() either.
Major changes: do not delete and recreate markers and curves for every tempo map
change, attach tempo curves directly to their (preceding) tempo marker, notable
cleanup of TempoCurve class to remove unnecessary members.
More tweaks expected since algorithm for matching markers and tempo map
points is not correct yet.
Editor::drop_regions() creates a new RegionInsertDrag()
with the region to drop to the timeline.
RegionInsertDrag is-a RegionMotionDrag is-a RegionDrag is-a Drag.
However the region does not yet exist on the timeline and
RegionView is NULL.
This will likely need an API change. e.g.
Directly pass the TimeDomain as argument. The information can
be provided by the region, or from the TimeAxisView or RouteUI
when dropping a new source/region.
Important logic from 6.9 was either missing or incorrectly implemented. New
version is much simpler - we just use the RoundDownMaybe mode of round_to_bbt()
to ensure that the note start is always within the current grid even if the
mouse is more than halfway "through" it.
MSVC is happy to ignore the above pragma although it aborts the build if it encounters #warning
#pragma GCC warning seems to work fine here for Clang - so start by changing just 1 x file to see if there's any detrimental effect for the other builds.
