* This function is

* and coordinate the overall timeline layout. Within these passes, each element
* starts with the (vertical) extension as allocated by GTK; typically these values
* need to be increased slightly, in order to align the track headers and the track
* body display, and to accommodate the clips and effect placed into each track.
* Such local adjustments will typically re-trigger the custom drawing code, and
* thus re-invoke this function, until the overall layout is stable. In a similar
* vein, the expanding or collapsing of clips and even whole sub-track scopes
* will cause adjustments and a re-evaluation.
* @warning care has to be taken to not "overshoot" each adjustment, since this
* might lead to never ending re-invocations and "layout oscillation".
