* Moved some actions to match the file organization: actions are in the order they appear on a qwerty keyboard
* Removed actions for F1 and F2, these were hiding View actions
* Removed action H for hide, which was conflicting with play-selected-regions
* Moved the grouping of jump-to-mark actions into Moving the Playhead
Designed to allow derived classes to *save* a different value
than would be reported by ::get_value().
Specifically there so that slaved controls can save/restore
their *own* state, not the value that ::get_value() would
return.
Not used because it turns out that the model in the GUI
needs to be based on axisviews, some of which correspond
directly to Stripables and some do not
- wysiwyg (during drag) when dragging more than one note across
a tempo change.
- introduces a muscal equivalent of snap_delta (only used for
note drags atm)
- split earliest note in selection into a separate function
- MRV::copy_selection() returns the equivalent _primary note
to avoid offset hell.
- RV::snap_frame_to_frame returns a MusicFrame
- prevent note drag moving before region start.
- don't add a new SysEx canvas item every time we zoom or drag.
- speed up redisplay generally using PatchChange-like method
for finding items (find_canvas_sys_ex() in boost::unordered_map).
- its still a fake event, but we can at least get the snap correct.
- playlist->add_region() parameters were whacky
(for Playlist::add_region_internal()?)
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.
