Windows managed as Proxy do not need direct calls to set_session().
This is already handled by WM::Manager::instance().set_session()
Also WM set_session() called it twice.
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.
There are two cases:
(A) Proxy is created first, dialog is created later on demand
(B) Dialog is created and directly registers its window as proxy
In (B) the dialog is usually on the stack and destroyed when the
ArdourDialog instances leaves scope. In that case ~ArdourDialog()
is called and the proxy remained.
Destroying the proxy does destroy the registered window in ~WindowProxy()
If ArdourDialog's d'tor itself deletes the proxy it would recurse into
itself. Existing APIs e.g. drop_window() likewise delete the window and
cannot be safely called from ~ArdourDialog.
For whatever reason, almost none of gtk2_ardour will compile (with MSVC) unless 'lua_script_manager.h' gets #included by 'gtk2_ardour/window_manager.h'. No idea why... :-(
I would have loved to split this apart, but there are just so many interrelated changes,
it makes little sense and would be a huge effort that would break future git bisect
use because so many intermediate commits would not compile
