GLOWCOLOR

THE BOX'S MAIN HELP:

This shader returns a glow, which falls off as the angle
between the two vectors grows.

II (input):

This must be a vector.  
The default is the opposite of the camera vector, -I.
When this vector and the NN vector point in the same direction
the glow is at its hottest and falls off as the angle between them grows

NN (input):

This must be a normal.  The default is the surface normal, N.
When the II vector and this vector point in the same direction
the glow is at its hottest and falls off as the angle between them grows

ATT (input):

This must be a float.  The default is 2.0.
This is the attenuation of the falloff.

GLO (input):

This must be a color.  The default is WHITE.  This is the glow color.

OUT (output):

This function returns a glow, which falls off as the angle
between the two vectors grows.
