If the View is modifiable, any transformation applied using either the
Navigator Manual Control window, or the Animator Manual Animation window
will affect the View.  The View can always be modified using the Navigator 
Projection window, regardless of the modifiability setting in the Object Control
Control Settings window.  Visibility has no meaning for the View.

If a Volume is Visible and it is visible from the current View location, 
then it will appear in the Navigator Projection window, and in any images
created.  If the object is not Visible, it will not appear in the
Navigator Projection window, and will not be considered when creating any
images.

If a Volume is modifiable, any transformation applied using either the
Navigator Manual Control window, or the Animator Manual Animation window
will affect that Volume, regarless of its visibility setting.  (Even if you
can't see the object, if it is modifiable, it is being transformed.)  
Also, when loading a texture, the texture will be associated with every
modifiable object.  There is currently no way to disassociate a texture from
a volume.

If a Light is Visible, then it will be considered when generating the Navigator
Projection window image, and any images created.  If the light is not Visible,
then it is considered to be turned off.
