Implement virtual method TEveElement::CopyVizParams(element) for the

following classes: TEvePointSet, TEveLine, TEveTrack, TEveTrackList
and TEveStraightLineSet.

Implemented TEveProjectable::PropagateVizParams().

In TEveGedEditor::Update() call PropagateVizParamsToProjecteds() so
that all representation of given element receive the potential
updates.
