the rest from `tools/convert_boost.sh`.
* replace boost::function, boost::bind with std::function and std::bind.
This required some manual fixes, notably std::placeholders,
some static_casts<>, and boost::function::clear -> = {}.
This allows UI scripts (saved in preferences) to access
os.* functions (non-sandboxed), while preventing other
scripts to do so.
Lua scripts that can run os commands can execute arbitrary
code on the system. While this is a nice feature, it can be
equally dangerous.
* remember window visibility, size and position
* Show as toggle in the window-menu (rather than show action)
* reduce specialization, use WM and ArdourWindow infrastructure
(transient parent, window-type, etc)
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.
Compare to f83dbf83. We cannot use an ArdourWindow here (which
would do this automatically) since we don't want any keyboard-event
forwarding from this editor-window. It's also a main window, not
a WM::ProxyTemporary.
