* Draw antialised waveform if waveform is monotonic
* Fix center-line position (span at most height - 1),
* Remove invalid "side-lines" that were previously
drawn around spikes.
* Do not linearly center min/max when drawing log-scale
* Fix offset of lower outline and clip indicators
This is all done in the GUI, using GUI objects. THe primary goal
here is to allow actions to be applied to selected triggers, so
there's no real need for a trigger aspect to libardour (core)
selection.
This was changed in fc9840f2a9 to hard code a "false" argument describing
whether or not the child bbox had changed. This causes the parent to not
recompute its own bounding box when a child is shown/hidden, which is
incorrect. We now force it to true, which may be overkill for some purposes,
but at worst will just force an unnecessary bbox re-computation and nothing
more.
Important logic from 6.9 was either missing or incorrectly implemented. New
version is much simpler - we just use the RoundDownMaybe mode of round_to_bbt()
to ensure that the note start is always within the current grid even if the
mouse is more than halfway "through" it.
When loading a session, we now just set up port state, which will
populate the Port::_connections member, and then once all ports have
been created, use PortManager::reconnect_ports() to get everything connected.
If connecting ports using the port-engine fails,
ardour forgets the connection.
Internal backends only produced an error if a port was already
connected, when using ::connect (handle, other), but
ignore already existing connection when using port-names.
Various ports are connected twice when the engine connects
at session load. This worked fine for as long as the engine
was never stopped (saving the session asks the port-engine),
but failed when the engine went away and internal representation
is used.
During initial setup, PortManager::reestablish_ports(),
the jack client is not yet active and port_connect failed:
"Cannot connect ports owned by inactive clients".
Later hotplugged devices were likewise not connected because
"JACK: Cannot callback the server in notification thread!"

A physical input port must remain connected to ardour's
physical_midi_input_monitor_enable port, otherwise reading
its input can cause crashes.
Previously a MIDI input port was disconnected from all other
targets when "MIDI input follows selection" was enabled.
