This completes the initial implementation round for the TrackHead.
- arrangement and layout for nested sub-Tracks is now settled
- a graphical representation of scope nesting was implemented
Postponed for later...
- still some minor discrepancies on synchronisation of vertical space
between TrackHead and custom drawing in the body (off-by-one?)
- Expanding / Collapsing of Tracks
- Implement actual Controls to influence the Scope, e.g. Volume, Mix-Mode
- Dynamically indicate selection and Muting on the structure display
- pick up all relevant values from CSS
- also control the width of the StaveBracket
- observe the given overall height
Moreover, complete documentation drawing in Inkscape
and add a page to the TiddlyWiki, describing the principles
underlying this design and construction.
