Variable facet dimensions

[mattbrehmer]

Currently facet dimensions are uniform and are based on the facet with the most number of tracks. However, in cases where one facet has a disproportionate number of tracks (due to many concurrent events), most of the other facets are empty white space. Each facet could be sized proportionally to the number of tracks; this would affect facet height for linear representations, and both facet height and width for radial and spiral representations.

A side effect of resolving this issue would involve non-uniform row and column dimensions for radial and spiral faceted timelines. A potential workaround would be to make the facets themselves drag-able and align-able using guides relative to the center or top/bottom/right/left of each facet, a la PowerPoint.
