// Class cf_3DTextMarker abstracts a set of graphable 3D points, marking
// the endpoints of a "text marker line", and associated text that will be
// displayed at the end of the text marker line.
//
// cf_3DTextMarkers will generate their text output (i.e. labels)
// using a "current Text Mark Font" pushed by the owner object,
// e.g. a cf_3DTextMarkerSeries or a cf_3DGridTickSeries...
