public abstract class TransformTool
This class is the base class for tool roots which manipulate
transformable objects (objects having the attribute
Attributes.TRANSFORM
).
The tool coordinate system (see ToolRoot3D
is adjusted such that tool nodes of size 1 have a size of about 150
pixels on a 3D view.

, e.g., they may set a certain scaling factor
between tool coordinates and camera coordinates in order to
ensure a fixed size of tool nodes on the 3D view.
