This reverts commit b3722f7063.
In some cases ardour shows context-menu on right-mouse-button
release. In this case selecting a menu-entry should happen
with the left-mouse button (or any button?!)
Using ev->button is only correct if the menu is temporary and only
visible while the button is held, button release then activates the
menu-item.
This needs further work, in some cases allowing any button (0) to work
makes sense and overall consistency needs to be improved.
Different places use different strategies for context-menus which
don't always match the button used in the event-handler.
This is a hotfix (to make TAV context menus work again with left-click)
* consistent behavior (Route, VCA)
* non-modal
* a single color picker for each RouteUI/VCA at most
* fix bug: VCA picker staying around even when VCA was deleted
controllable->set_value() from GUI context will eventually queue
a session-rt command. By the time the realtime command runs, the
controllable needs to be in "touch" mode.
The AutomationController "toggle" UI worked around this by directly using
the underlying API (ignoring slaved-controls and ignoring groups).
The RouteUI's GUI wasn't able to write mute-automation at all.
This commit is a compromise: press + hold (touch) + release button.
(it may need further special-casing for _desc.toggled in
AutomationControl::actually_set_value(), also undoing automation-writes
is currently not working correctly)
