An object of class Eye represents a/the virtual Eye point of
of the scene displayed. The main eye point object is created
on initialization and accessible using taccgl.stdEye.
In 3D/WebGL mode currently taccgl™ supports just this single eye.
In 2D mode there can be additional eye points and it is possible
to select an eye point per transition. Normally these eye points
differ in their origins. This feature is useful to overcome
limitations imposed by the parallel projection used by 2D mode,
New eye point objects can be created using createEye and Eye.clone.
