/** @file gtk-canvas-experiment.hpp
** A custom widget using a canvas to draw and to place widgets.
**
** ## planned design 2/2017
** The architecture of the UI is in a state of transition right now, working towards the goal
** of interconnected layers and an operative session and engine. Within the new control structure
** about to be built, there is an UI top-level circle of managing entities to handle global concerns
** and actions. The ctrl::InteractionDirector incorporates the role of _model root_ and thus manages
** a collection of timelines. The timeline panel exposes this collection and allows to view and
** interact with one of the given timelines. The build-up of the timeline display and thus the
** initiative to expose a timeline comes from the interaction director -- but as usual with
** graphical user interfaces, any user interaction after this point is handled autonomously
** by the gui::timeline::TimelineWidget and gui::timeline::TimelineController
**
** @todo as of 10/2016 this is WIP-WIP-WIP : canvas widgets experiment
** @todo as of 10/2018 we start to build a new timeline widget, connected to the UI-Bus
** @remark as of 10/2018 we start to build a new timeline widget,
** based on this technology demo.
