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.

RouteTimeAxisView
Now that we have VCATimeAxisView, this needed to be done, but it also potentially applied with automation

This had become incoherent over time, and posed a development hazard and burden going forward

- removes the need for 'pixel hunting' wrt NAME_HIGHLIGHT_SIZE.
- new control points generated by clicking on a line are placed
where the verbose canvas cursor says they are.

Currently when a GhostRegion is deleted by its "parent" RegionView it emits the
static GhostRegion::CatchDeletion signal which is connected to the
RegionView::remove_ghost method of every RegionView instance.
With a static GhostRegion::CatchDeletion signal a particular test session
causes 31 Million calls of RegionView::remove_ghost on Session deletion and the
session takes 70 seconds to close with a debug build.
The lifetime of a ghost region is tied to both the TimeAxisView(TAV) and
RegionView(RV) in that when a RegionView is deleted all GhostRegion instances
associated with the RegionView should be deleted or when a TimeAxisView is
deleted all ghost regions that are contained in the view should be deleted.
This means that there needs to be notification between GhostRegion and both
classes. Instead of using a signal for this as we know there are only two
listeners and GhostRegion already holds a reference to the TimeAxisView, also
take a reference to the parent RegionView in the GhostRegion constructor and
use it to notify the RegionView when GhostRegion destructor is called so it can
drop any references it holds.
Using a direct function call in the GhostRegion destructor to notify the
TimeAxisView and RegionView "parents" brings the unload/close time down for the
test session from 70 seconds to 4.5 seconds.
The GhostRegion also references canvas items that are added to the TimeAxisView
canvas group or at least a canvas group that it manages. So when the
TimeAxisView is destroyed and the canvas group that is the parent of those
items is destroyed, the GhostRegion's canvas items will also be
deleted/destroyed by the parent canvas item/group. This means the GhostRegions
must be destroyed when the TimeAxisView they are contained in is destroyed or
there will be dangling references to canvas items that have already been
deleted and trying to delete them again will be bad.

- disallow simultaneous events via ControlList::editor_add ()
- clicking on an automation line selects the points that define it.
- don't 'flash' a region selection when using mousedraw mode.
- cp click selection resembles region selection.
- region gain points respect snap modifier (a la automation points).

Fixes background peakfile/waveform creation. Waves need to be
created directly with the proper attributes as set by StreamView.

switching to Grab should show the fade handles...
...switching away from grab should hide them.
Also, change "always show gain" preference to show lines, but not control points.

Visibility is driven by the currently selected mouse mode.
Visibility no longer depends on entering/exiting the region.
Range mode shows the lines but not the points.
Fixed option text to reflect new operation.

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.

IMPORTANT: names have not been downcased and spaced yet, so many colors are not found

There might be a few special cases lingering around from attempts at magic tool
business, but this seems to work fine as far as I can tell.

This mitigates issues introduced with 3.5-3406-g90872c2
but is not a final solution. The x-axis is still broken.
