** As result, some new widgets may be injected, existing widgets might be removed or
** hidden, and other widgets may be relocated to different virtual canvas coordinates.
**
** ## Coordinate systems
** When drawing onto a canvas, we need to define the coordinate system. This task is
** complicated here, since -- on implementation level -- we end up with several `Gtk::Layout`
** elements (the actual canvas widget). This is necessary to accommodate for the display
** "mechanics": part of the timeline has to stay "pinned" on top, including the time
** overview ruler and possible further marker displays. Based on practical considerations
** we decide to handle this situation as follows
** - Each drawing canvas gets its own coordinate system; its extension is defined to
** match the size of the scrolling area, and coordinates are adjusted so to match
** drawing primitives and coordinates of attached sub-widgets
** - However, the timeline as a whole constitutes a global coordinate system on its own.
** It is the actual drawing codes's responsibility to translate into canvas coordinates.
** - To hide those complexities from the display management code, we introduce an abstraction
** model::ViewHook. This allows to place sub-widgets _relative_ to each track locally.
** So effectively, from the view point of (sub)widget management, we thus get virtual
** canvas coordinates per (sub)track.
**
** @todo WIP-WIP-WIP as of 6/2019

* Presentation of the timeline workspace by custom drawing on a canvas.
* This widget allows for uniform access and handling of that body area;
* however, in fact we need several TimelineCanvas spaces, since part of
* the display needs to stay "pinned" on top (the overview rulers), while
* the majority of the track body area is packaged into a scrolling pane.
*
* ## Interface
* We have to distinguish two kinds of drawing access to this BodyCanvasWidget:
* - painting of areas for background, profile and for overlays
* - relative attachment of widgets onto this canvas
* For the former, we use the TrackProfile as a drawing Visitor (double dispatch):
* The layout code identifies a sequence of spaces (horizontally extended) corresponding
* to tracks and rulers. This is abstracted into the profile, and can then be (re)rendered
* as often as necessary by "playback" of this profile.
* On the other hand, for attachment of sub-widgets onto the canvas (Clips, Effects, Markers)
* we use the Interface model::ViewHook, which allows us to break down the access hierarchically.
* Each sub-Track can be outfitted with its own "virtual canvas", exposed as delegating ViewHook.
* @todo WIP-WIP as of 6/2019
