This is not used anywhere in Evoral and is just a wrapper around the PBD
RingBuffer anyway. Towards a (once again?) independently buildable/testable
Evoral and fewer cross-dependencies.
for one, it can mess up the value when switching to
numeric-entry. It is also rather useless and not
Fader-like (faders are not scrollbars).
Besides, "stepvalue" is way to large and causes jumps
(sometimes step-value is even negative, see
"fast lookahead limiter", "release time"
-> some other bug)
fixes crashes:
* If the Editor-Mixer shows a channel with a plugin that
has been edited in the Mixer, double-clicking the plugin
will try to bring up a 2nd instance of the plugin-UI.
* When closing Ardour both the Mixer and the Editor-Mixer try to delete the underlying plugin, resulting in a double free.
This probably isn't correct in several ways, but it works more than it did, so
I figure it's push worthy.
Still not working:
* Saving mute automation list
* Dragged control points are not snapped to model restrictions
(boolean, in this case, but general problem)
* Line goes funny if you record mute automation
(as opposed to drawing it which works)
This was necessary due to a bug/design issue between Glibmm and Glib (see https://bugzilla.gnome.org/show_bug.cgi?id=561885)
but the problem needs to be managed by the *creator* of the IOSource and that has now moved inside CrossThreadChannel.
This is pretty kludgy but we need the UIConfiguration object (or any color management object) to be the first to connect to
the ColorsChanged signal.
Might be better to make the UIConfiguration object a delegate for the ThemeManager.
