Abstract base class for viewer manipulators, which allow direct in viewer manipulation of a (TGlPhysicalShape) object - currently translation, scaling and rotation along/round objects local axes.

See derived classes for these implementations.

This class provides binding to the zero or one manipulated physical, hit testing (selection) for manipulator sub component (widget), and some common mouse action handling/tracking.
