gtkmm2ext/keyboard.cc has a special case to emit a signal on the key-up of
the modifier key used to adjust track heights in conjunction with the
scroll wheel, so that the same track continues to be resized even when
it's shrunk to no longer be under the mouse cursor. However, this code
assumed that the modifier key for this was <Shift>.
Fix it to use the event->state bit corresponding to
ScrollZoomVerticalModifier instead, and rename the relevant functions to
clarify that it's the 'zoom vertical' modifier key they're dealing with.
Partially fixes#5610.
when using ImportDistinctChannels, correctly name regions so that playlists for each channel/track
are also named differently, and thus reloaded properly when the session is reloaded.
* display metrics for every used meter-type
* show metrics between meters with differnet types
* update text and label alignment for meterbridge
* fix crash when deleting metrics-strip (zero route)
* clean up metric pattern code (use float for dBFS)
Gtk::FileChooserButton::add_shortcut_folder() throws a Glib::Error
exception if the folder being added already has a shortcut, causing the
'New session' dialogue to appear empty when choosing 'New...' from the
Session menu. This happens if Ardour's default session folder is
set to a location that has a standard shortcut in the Gtk file chooser,
e.g. the user's home directory, desktop, &c.
Catch the exception in ArdourStartup::setup_new_session_page(), so that the
'New session' dialogue appears as expected, and likewise in
ARDOUR_UI::open_session() to avoid a similar problem there.
Fixes#5591.
