If time domains differ, it is necessary to first convert the argument duration into a duration
at the position of "this", in the correct time domain. Then we recursively call the operator
again, but this time we will use the fast path that just adds two timepos_t values.
This fixes async callback from CoreAudio via
AudioDeviceAddPropertyListener. Apparently in rare cases it can
happen that the property listener calls back concurrently with
processing on M1 machines using Rosetta.

May also be caused by plugin(s) taking a long time to
change buffersize. Processing continues even though the
buffersize callback has not yet completed.
PS. I have not been able to reproduce this on an Intel
machine, even with excessive buffersize changes. However
since buffersize changes cannot (usually) happen concurrently
with processing, taking the lock is reasonable.
Some plugins have a min/max range of 1, for stepwise enumerated
values of a control. e.g. waves maps note-names this way.

pbd/i18n.h MUST NEVER be included from header files and always be
the last include. This is because `_` is declared other headers
notably boost and some apple headers.
leading to issues like
../libs/pbd/gettext.h:58:27: error: expected unqualified-id before ‘const’
58 | # define gettext(Msgid) ((const char *) (Msgid))
Makes it slightly easier to read+parse what is happening. Yes, for a
Sequence property, the call could apply several changes, but overwhelmingly
it is used to apply a single change.
After the editor is attached as tab to the main window,
looking up keyboard bindings using get_toplevel() no longer
works.
This uses the widget-hierarchy just like ARDOUR_UI does.
It turned out that 'boost::intrusive::list_base_hook<>' won't compile if its parent class is declared using '__declspec(dllexport)' - so rather than exporting each entire class, let's use the alternative approach and export the various class members individually.
list_member_hook<> is very troublesome in MSVC and is known to cause problems in other compilers when used inside a class which has a virtual base class.
This fixes an issue with adding/removing tracks while auditioning.
Session::remove_routes() calls Graph::clear_other_chain(),
which will block until the graph chains have been swapped.
