Timeline: determine remaining work to wrap-up

Browse source 
Intention is to shift focus of development work down towards Player and Scheduler soon.
However, since the timeline display saw substantial improvement it seems prudent
to finish work on some open ends, notably

- the track head structure
- the drawing and styling code

While content rendering for Clip widgets can safely be postponed, regarding the TrackHeadWidget,
where custom drawing is planned to display a structural outline of the nested scopes, some
ground work should be completed to make those plannings explicit.

/** @file stave-bracket-widget.hpp
** Widget to group tracks visually in the Timeline presentation.
** The TrackHeadWidget is structured according to the nested structure of tracks
** in the Fork, using nested widgets to represent sub-tracks; in the grid's first column
** a graphical structure is rendered to indicate the nesting and connectivity of tracks.
** While based on few rather simple visual primitives, this structure need to adapt to
** the actual space allocation and positioning of sub-tracks in the layout; technicalities
** of actual drawing this structure is abstracted into this custom widget — allowing the
** track head to indicate the necessary layout constraints generic and recursively.
