* Resolve ambiguity between typef'ed ARDOUR::timepos_t and
Temporal::timepos_t (and timecnt_t, superclock_t)
* Add missing classes TempoPoint, MeterPoint, which are
return value for various TempoMap methods.
* Change TempoMap into a shared_ptr<> class.
* Move Tempo and Meter out of ARDOUR into Temporal namespace.
* add various bindings to access the TempoMap
* move Temporal enums out of ARDOUR::Temporal namespace
This is mainly for the benefit of Lua bindings, but also increases
overall API naming consistency with functions and methods
`is_XYZ()` being used elsewhere.
This API change breaks builds!
If there's a grabbed item (GtkCanvas only at present) then unless it belongs to the scroll
group used for scroll offset translation, the event coordinates should not be translated,
even if the mouse pointer moves into the scroll group.
The connection was stored by the Port where it was initiated from:
1. Connect A to B
2. Disconnect B from A
(1) Port A remembers the connection to B
(2) Port B does not know about the connection from A
Since disconnect is initiated on port B, port A still retained
the connection information.
When restarting the engine, Port::reconnect() reestablished the
connection.
This is only relevant when libardour's own connection information is
used. e.g. the session is closed without engine, or when re-starting
the engine while the session is open.
Changes include workarounds for weird Rubberband API (pad, drop, truncate requirements),
and a shift to push logic after a slot is finished back up into the TriggerBox.
Not finished yet, some easily encountered bugs remain
::snap_to() was intended to round a Beats value to the nearest multiple
of another Beats value. It did not do that, but instead rounded down.
Worse, it used Beats::operator/ which in turn uses int_div_round(),
which is incorrect for a situation where we need integer truncation.
The changes fix the actual arithmetic and add 2 variant functions so that the
API includes round down, round up and round to nearest.
max_samplepos and max_samplecnt and both INT64_MAX which is (a) too large to fit into a signed 62 bit
integer and (b) definitely too large to be represented in a signed 62 bit superclock value.
Move the constructors that use samplepos_t into the .cc file, and treat these two values as special
cases that mean "as large/late/huge/long as possible".
