Define here the text visual aspect.
Style
Gamgi supports 
Wired stroked fonts and 
Solid
extruded fonts. Stroked fonts are faster and are more suited for
analysis. Extruded fonts are made from TrueType faces and are 
designed for final presentations.
When a new 
Style is selected, the 
Face menu is 
automatically updated, showing only the fonts available for 
the new 
Style. The default font for the new 
Style
is automatically selected.
Face
Currently GAMGI supports 14 stroked fonts:
1) Roman and Roman Monospace;
2) Sans and Sans Bold;
3) Serif and Serif Bold;
4) Script and Script Bold;
5) Gothic English, Gothic German and Gothic Italian;
6) Symbol Sans, Symbol Serif and Symbol Serif Bold.
The first two were made for Sun, used by the X consortium 
and currently distributed with GLUT and freeglut packages.
The 12 other fonts were digitized by Allen V. Hershey, used
by several packages and currently distributed with GNU plotutils.
Currently GAMGI supports 10 extruded fonts:
1) Sans, Sans Bold, Sans Italic and Sans Bold Italic;
2) Serif and Serif Bold;
3) Mono, Mono Bold, Mono Italic and Mono Bold Italic;
The typefaces for these 10 fonts were made by BitStream, 
with the name Vera, for the Gnome project.
R, G, B
The 
R, 
G, 
B entries define the text color,
from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0).
Scale
Set the text size, including its child objects. Text objects are
scaled around the text 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.
