previously if some audio region was locked and locked to video,
the audio-region always stayed put and the video could only be
moved forward.
TODO: add an "unlock all" option.
- also allow moving of automation lines in internal mouse mode.
- this is also a first pass at ensuring that if an operation does
nothing, avoid an undo entry.
- don't keep setting/unsetting write pass when transport frame
remains the same (think larger jack buffer sizes)
- insert guards are now 64 frames after when.
- refactor previous approach.
- its now possible to use snap modifiers in combination with others
afaict this hasn't worked for some time.
- use "contains" rather than "equals" during drag. Still uncertain
about this wrt beginning a drag. for now they are all "equals".
- probably solve the "snap modifier modifier" problem using
ArdourKeyboard::indicates_snap () and friend.
- Also makes "Mod4" Appear as "Windows" and adds new combination
"Alt-Windows" to the dropdown.
- Attempt to set a pair of default snap modifiers (without
knowing what it actually is for OSX)
- Copy modifier now saves
- Snap modifier modifier problem still remains.
- Copy modifier still doesn't save
- Testers please edit the Extra section of ~/.ardourN/config to allow
defaults to "take"
- Note that the current defaults overlap.
- warning - absolute snap modifier has no default and will be always
"on" unless you set it!
Note that no defaults are set - go to prefs->user interaction to
ensure that nothing is set to "no modifer"
also - the copy modifier doesn't actually save its state yet.
- user can abs/rel modifier key in prefs->user interaction
suggested for linux - absolute->alt ignore snap->alt-shift
- Constrained mode works the same as button 2 drag (initial move
sets constraint axis).
Button 2 drag now is constrained to initial move axis, removing
all modifiers from this op.
Remove Jump after trim mode.
TrimDrag now has:
Primary for trim anchored to fade.
Secondary for contents trim (as before)
Primary & Tertiary for "non overlap" trim
All drags have Tertiary for relative snap
* Handle large (delta > 1) movements into the DZ
which are not due to invalid-drop positions, but
caused by laggy GUI or rapid user movements.
* ignore busses when moving out of the DZ.
Allow to drag multiple regions from different tracks
to/from the dropzone.
Busses & Automation-lanes are ignored, as are
hidden tracks.
Any region may serve as mouse drag anchor.
