Change here the visual representation for a single plane or a list of planes.
To modify a plane, click over its graphic image, or write its identification
(name and number) on the 
Plane entry. To modify a list of planes, press
the button 
List (after creating the list of planes with 
Plane->Select).
Parameters for empty entries or 
Local choices remain unchanged.
To change a plane name write the new name in the 
Plane entry,
followed by the plane number (GAMGI needs the number to identify the plane).
To change the name for a list of planes, press 
List first
and then write the new common name in the 
Name entry.
R, G, B
The 
R, 
G, 
B entries define the plane color,
from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0).
Scale
The 
Scale factor can be used to change a plane size, including
its child objects. Plane objects are scaled around the plane center.
The visual representation of an object is always scaled by its own
scale factor multiplied by the scale factor of all its parent objects
until layer, inclusive.
