Better version of 817fccb3e5, the visibility should not depend
on the number of items in the dialog, but its requested height
vs screen height.
The main use-case is to not show the scroll-bar if the dialog has only
a few rows. Then again if the scrollbar is visible, the dialog
should not shrink below a reasonable min. height.
This fixes various issues, esp on macOS and Windows where
the window is only hidden, not re-stacked:
* plugin scan dialog hides the splash, but
the plugin-manager emits BootMessage
(this worked mostly because gtk event loop didn't
have time to catch up)
* More than one dialog can pop back/front the splash,
e.g. scripted session-setup or error messages when
loading recent sessions.
Copyright-holder and year information is extracted from git log.
git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
This fixes an issue on MacOS/X to only show non-root volumes in
the file-open dialog. They're just as valid for save-as, export, video
files etc.
In case of a 2nd internal disk, it is also a valid choice as default
folder for new sessions.
When a non-existent file-path is given, GTK falls back to show the
containing folder and automatically goes up to parent folders until
the root.
This removes the explicit file/folder check and delegates the
behavior to GTK, allowing to set a folder for a non-existent file.
