preparation for further Summary and Number of visible
track count fixes.
* “Only Self”: don’t resize child-views (old default)
* “Total Height”: distribute height equally among
all visible child [automation] lanes
* “Height per Lane”: given height should be applied
to all sub-views.
Fixes bug #0006138. This solution does make the other label move when settings
are changed (presumably what the fixed width stuff was for), but I don't think
this is a big deal. Lesser of two evils, at least.
Fix several other cases where a single mouse click could cause several
(not nested) selection ops.
Fix missing selection memento for midi notes and midi commands.
Rename some variables.
Fix random style issues.
Unfortunately we store the state of models as simply model, so if there's ever
duplicate model names, we're somewhat screwed, but this makes the (previously
unmanageably huge) menu usable, while retaining the "model name as global
identifier" state unmodified.
Fix some inaccurate/misleading comments that led to said bug.
Gracefully handle the "impossible" case where we can't figure out a state ID
for an automation track, instead of crashing.
No functional changes in this one (for easier auditing), but towards having
round up/down only if necessary modes, rather than kludging around that
situation with a double round as we do currently.
This takes a VERY long time to do, so is probably a problem for defined devices
with a ton of channels and devices, too. Not sure what the smart thing to do
here is, though adding lanes really shouldn't be this slow in the first place.
Existing code would cause data loss due to creation of two Source objects referring the same path, one with removable flags and one without. Careful code review suggested a variety of thinkos, function naming problems and other confusion that caused this. I have tried ot extensively comment what is going on with these operations, because it is one key area in which MIDI differs from audio: with audio, capture is the only way to add a new audio region, but for MIDI there are GUI input events that can add a new region.

initial working version after changes to MIDI channel filtering. may affect metering input too. testing not yet finished
this commit merges many deep changes in ardour's internal architecture,
combined with a total redesign of how MIDI channel filtering works.
data in a track used to flow from JACK port buffers to diskstream's ringbuffers
and was then copied from the ringbuffers into a BufferSet for use during
Route::process_output_buffers(). The butler thread would handle the movement of
data between the ringbuffers and disk.
with this commit, data now flows from JACK port buffers into the BufferSet used
for Route processing, and is copied from the BufferSet into the diskstream's
ringbuffers (the butler thread continues to handle interactions with disk as
usual).
this change allowed a dramatic consolidation of code and simplification of most
aspects of Track/Route::roll() and Track/Route::no_roll(). in particular, see
Route::fill_buffers_with_input() which now concisely describes how we move data
from JACK port buffers into the BufferSet for all Route types (including Tracks).
this work was initially motivated by changing MIDI channel filtering so that we
can process capture and playback independently. there is now a very clean
pathway for this - see MidiTrack::roll() (NOTE: This needs implementing in the
no-roll case too - a TODO item).
the channel selector for MIDI tracks has been moved out of the track header and
is now accessible via the context menu. more work is likely here, to make it
(more) obvious to the user when filtering is going on.
