/**
 * All dynamic drawers have to extend this class.

 * 

 * Getter methods for the shapes (GetSegment(), GetTriangle(), etc.) return a
 * ref to a stored shape.

 * e.g. After you add a triangle (id = 100),
 * drawer.GetTriangle(100).GetVertex(0).SetPos(...) updates a vertex position in
 * the triangle.

 * This is true for all dynamic drawers as of v11.4.0.
