SingletonRef was only invented because lib::Depend (or lib::Singleton at that time)
offered only on-demand initialisation, but could not attach to an external service.
But this is required for calling out at the implementation side of a
Lumiera Interface into the actual service implementation.
The recently created DependInject::ServiceInstance now fulfils this task way better
and is seamlessly integrated into the lib::Depend front-end
this is just a tiny change to make things more othogonal.
Now the unwinding and calls to any GTK / Widget dtors happen *after*
emitting the term signal from UI shutdown. Which means, the other subsystems
are shutting down (in their dedicated threads) as well, thus lowering
the probability of some action still using the UI and triggering an exception
Gtk::Main is deprecated, but the new solution, instantiating a
Gtk::Application object does not match our use case, since we handle
all application concerns already and just need a Gtk main loop to run.
Anyway, it became clear that the "main object" will be the new UiManager.
As a first step, I've now moved the (deprecated) Gtk::Main object
down there. Next step (planned) will be to inherit from Gio::Application
and clone some functionality from Gtk::Application
This is a very pervasive change and basically turns the whole top-level
of the GTK-UI bottom-up. If this change turns out right, it would likely
solve #1048
WARNING: in parts not implemented, breaks UI
...which itself is obsolete and needs to be redesigned from scratch.
For now we create a local instance of this obsolete PlaybackController
in each viewer panel and we use a static accessor function to just some
instance. Which would break if we start playback with multiple viewer
panels. But we can't anyway, since the Player itself is also a broken
leftover from an obsoleted design study from the early days.
so why care...
as a rule, one should not rely on "using namespace xyz",
since this makes organisation of minimal header includes near impossible.
You end up with mass includes in some "top level" headers, resulting
in painfully slow compilation turnaround times.
In exceptional cases, using namespace foo might be adequate though
There seems to be a mismatch in the arrangement of the top-level entities
* we support multiple windows, yet from reading the code, you'd ge the impression we aren't really aware we have multiple top-level windows
* the `WindowManager` is the core UI manager, which feels like a mix-up in concerns
* the `WorkspaceWindow::createUI()` does the global UI initialisation. Again, we have multiple workspace windows.
* `GtkLumiera::main()` creates a `Model` and a `Controller` in local function scope, but stores the `WindowManager` in an object field.
* it seems, for that very reason, `GtlLumiera` needed to be a singleton, to allow by-name access to "the" `WindowManager`
* needless to say, this causes a host of problems when shutting down the UI.
The idea is to introduce a dedicated UiManager, to deal with the central
framework induced concerns solely, and to demote the WindowManager and the
WorkspaceWindows to care only for their local concerns
Decision was made to use the CoreService as PImpl to organise
all those technical aspects of running the backbone. Thus,
the Nexus (UI-Bus hub) becomes part of CoreService
reason is, only files with a @file comment will be processed
with further documentation commands. For this reason, our Doxygen
documentation is lacking a lot of entries.

This is a development snaphot pre release of Lumiera.
It features codebase maintenance, upgrade to C++14 and GTK-3
and some work towards a Proc-GUI connection (unfinished)
Update README, AUTHORS, LICENSE and similar release docs.
over time, a specific Lumiera code writing style has emerged.
The GUI, as it stood, used somewhat different conventions,
which now have been aligned to the common standard.
Basically we use GNU style, with some adjustments for OO-programming,
we prefer CamelCase, and write TypeNames uppercase, variableNames lowercase
This is the first step towards a generic backbone to connect
any GUI elements to the session within Proc-Layer.
It is based on a spefic understanding of Model-View-Controller,
which turns the Model-Controller interactions into messages.
lib::Depend<TY> works as drop-in replacement for lib::Singleton<TY>
This changeset removes the convoluted special cases like
SingletonSub and MockInjector.
- split off the tricky basic GTKmm includes
- reduce the clutter in the gtk-lumiera.header
- make GtkLumiera a singleton, placed into static memory
- remove all static functions from WindowManager
- use custom builders
- clean up specification of target paths
- generated executable is fully relocatable
- read a bootstrap INI instead of compiled in searchpath
