Previously we were using a convoluted scheme of firstly setting the transport speed to 1.0, then later re-setting it to 0.0. On Windows this was having some strange side-effects (such as leaving the transport in Play mode and/or resetting the timeline to zero timecode). Hopefully this change will also work for the other platforms.
Pass 'true' to accept_on_focus_out of AudioClock, so that editing the
insert/remove time clock and then clicking elsewhere without hitting
<Enter> first doesn't mysteriously set the time back to 00:00:00.000.
If this parameter is passed as 'true', then edits to the clock will be
accepted when the user clicks away from the clock, rather than
unconditionally discarded as hitherto.
'Cut time' implies that the cut timeline items might end up on the
clipboard to be pasted somewhere: this isn't the case at present, so rename
the functions, class, &c. to say 'remove' rather than 'cut'.
Rename insert_time_dialog.{cc|h} to insert_remove_time_dialog while we're
at it.
Add options to move glued & locked markers to Editor::cut_time(), in line
with the insert_time() implementation.
Fix up the order in which operations apply to range marker start & end
points, to avoid problems when a range which lies after the cut point is
shorter than the length of the cut.
When inserting time and moving a range marker, move its end first, before
moving its start, so that if the time being inserted is greater than the
length of the range, we don't try to set its start to after its end.
Due to some change somewhere along the road the nudge clock does
no longer fit in the transport-bar on 1024px screen with 100% font-scale,
even if the 2nd clock is hidden.
However, these days it does fit nicely on its default position even
with wide-editor-mixer on a 1024px screen.
Call update_config() after selecting/deselecting all tracks/busses so that
the warning about 'No channels have been selected' is shown/hidden
appropriately.
Now that there are 'select all tracks/busses' buttons, it makes sense to me
that stem export should start off with no routes selected, rather than all.
Maybe stem export should by default select routes that are selected in the
editor, but that's a task for another time.
The exported file is silent, when choosing to export either region contents or
track outputs, so there seems no point in making such routes available for stem
export at all.
Perhaps there's an arguable use case for enabling stem export of inactive
tracks, but I can't see that it's worth worrying about for now.
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.
Some refactoring was necessary to avoid code duplication
Restoring of device state for input and output devices still doesn't work
correctly. I'm not quite sure what the issue is at this stage.
