Change here the visual representation for a single direction or a list of directions.
<p/>
To modify a direction, click over its graphic image, or write its identification
(name and number) on the <b>Direction</b> entry. To modify a list of directions,
press the button <b>List</b> (after creating the list of directions with
<b>Direction->Select</b>). Parameters for empty entries or <b>Local</b> choices
remain unchanged.
<p/>
To change a direction name write the new name in the <b>Direction</b> entry,
followed by the direction number (GAMGI needs the number to identify the direction).
To change the name for a list of directions, press <b>List</b> first
and then write the new common name in the <b>Name</b> entry.
<h3>R, G, B</h3>
The <b>R</b>, <b>G</b>, <b>B</b> entries define the direction color,
from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0).
<h3>Scale</h3>
The <b>Scale</b> factor can be used to change a direction size, including
its child objects. Direction objects are scaled around the direction center.
<p/>
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.
