When deleting a range in ripple mode, ripple everything after the start
point of that range backwards by the length of the range, so that
newly-created regions immediately at the range end move back to the range
start.
Deleting regions (or ranges, or anything) shouldn't affect the contents of
the clipboard - only CutCopyOp::Copy, CutCopyOp::Cut and CutCopyOp::Clear
should do that.
Add a value for Ripple to EditMode enum.
Add Ripple edit mode to edit mode dropdown, by adding it to the
Editor::build_edit_mode_menu() helper function, and remove the old code that
added items to the (now unused) Editor::edit_mode_strings.
Add the regions that should be affected by the drag to RegionDrag::_views so
that the drag carries them along automatically.
Use a copy of the RegionList in Playlist::core_ripple(), since bad things
happen when iterating over regions and they get moved around in the list.
Handle rippling in removal of regions from playlist.
When dragging in ripple mode, exclude all regions that lie before the
original start position of the selected regions being dragged from
rippling: this is what Mixbus does.
Make editor dragging respect snap-to settings, by using the existing
compute_x_delta() function, which did almost the right thing. Move setting
of _last_frame_position out of that function so all ripple-dragged regions
can move.
Ripple when dragging from region list: even though Mixbus doesn't do this, it
seems like a good idea.
Prevent multi-track selection being dragged across tracks, by making
RegionMotionDrag::y_movement_allowed() virtual, and overriding it in
RegionRippleDrag to forbid dragging of selections containing regions on more
than one track to dofferent tracks in ripple mode.
Remember which TimeAxisView a ripple-mode drag that's allowed cross-track
drags started from, so that the effect of rippling regions after any region
that's dragged off that track can be undone.
Move clear_changes() of the playlist on which a region has been dragged
before calling set_layer() on that playlist, so that undo of region drags
in layered mode undoes any layer changes too.
Should fix#5904
If enabled, then the button simply changes the behaviour of the "play" button rather than actually starting playback. If disabled
transport behaviour should be unchanged from before.
This started happening more frequently after this function started to be called more often (which was the right thing to do, but
had this side effect (now fixed).
1) Make sure we create or open any files in binary mode
2) Make sure the user can see an error message of we fail to parse the command line
3) Make sure that the call to 'windows_vst_gui_init()' matches its declaration (i.e. only applicable when NOT on PLATFORM_WINDOWS)
