Because a lot of camera can be used in a scene with different role,  
and sometimes I want to see them and control them in the scene from the 
point of view of an other.

But the camera you see and control in the scene can be a kind of 
special 3D node that is a camera manipulator, not the camera itself...

And maybe the thing I am confused is the way the camera is designed is 
a mix of a 3D view plus the frustum camera, without being a view. Ok, I 
forgot that this way allow to connect the camera to an NSView or 
something else, hence doesn't depend on AppKit (it was the way I was 
trying to use gnistep+3DKit 2 years ago, when I was still in a graphics 
company :( ).

But it would be better to me to separate the view functionalities to 
the frustum ones.
