01.28.99      Wfmm Sphereglo
========      ==============

This material shader creates blends between two colors when used as a color shader, and between opaque and transparent when used as a transparency shader. 
It is intended for use with spherical objects (hence the name), and is particularly useful for glowing particle effects, as the output is always front-facing.

first color - the color that will be around the edge of the circle (color shader only)
second color - the color that will be in the center (color shader only)
attenuation - controls the rate of "falloff" from the center to the edge. A smaller value will result in a more gradual blending."


You can access sphereglo as a color shader and/or a transparency shader by
clicking the applicable shaderball in the material panels.  Right-click to
set parameters.

=============================================================================

* Should now update when used in layered colors shader - I've witnessed it
  occasionally only update the small color shader ball (and not the main
  preview panel) when you change a parameter for the first time only, but
  that shouldn't be something to worry about

* Changed color picker, now uses an RGB panel for each color. You can also
  grab a color from the screen by right-clicking the color button, the
  mouse pointer will change to a crosshair, and another click will select the
  color under the crosshair.
