+ ** Timeline presentation helper to organise drawing of the time overview ruler.
+ ** The scrollable body part of the timeline display relies on custom drawing onto
+ ** a ["widget canvas"](\ref TimelineCanvas) for the nested track content; above
+ ** this area we build a horizontal ruler to show the timecode and frame count
+ ** references plus any markers, ranges and locators. Since these need to be
+ ** aligned precisely with the content, we employ custom drawing for this
+ ** part as well. The TimelineRuler helper -- like any parts of the coordinated
+ ** TimelineLayout, are referred to from and used by the BodyCanvasWidget for
+ ** offloading specific parts of the drawing routines.
+ ** Actually, this space is just a working area and created by custom
+ ** drawing on the [timeline canvas](\ref timeline::BodyCanvasWidget);
+ ** yet for coordination of a globally consistent timeline layout, each
+ ** track display is coordinated by a TrackPresenter, which corresponds
+ ** to a session::Fork and directly controls the respective display elements
+ ** in the [header pane](\ref timeline::HeaderPaneWidget) and the display of the
+ ** timeline body, which is actually a canvas for custom drawing.
