In this section, the built-in widgets are presented.
In this section, the widget framework is explained. Widgets represent
2D or 3D objects, varying from simple ones such as lines to complex one such as
point clouds and meshes.

Widgets are **implicitly shared** . Therefore, one can add a widget to the scene,
and modify the widget without re-adding the widget.
