Detailed Description

A manipulator which position is driven from outside, and that use an "EyePos, Dir, Up" frame to set the viewpoint.

Can be used as a base class for other manipulators using the "EyePos, Dir, Up" frame. Dev Note : Internally, the FixedManipulator uses a left-hand coordinate system ; use SwitchLeftRightFrame() to switch internal vectors when needed.
