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

StarFlare Texture
Type:  Color, Filter.

This texture creates a star shaped lensflare out of a bright plane.
The z-axis of the texture is the direction of the light, so when the 
z-axis is pointing straight at the camera, the flare is the most intense.
You could make a spotlight, add a BRIGHT plane at the position of the 
lightsource (with the z-axis pointing in the same direction as the 
lightsource) add this texture and you have a real working starflare.
Of course you don't have to add it to a lightsource, just add it
anywhere, also it doesn't have to respond to the camera, just
experiment.

Requester:

Star Radius:                    Outer radius of the lensflare when z-axis is
                                aimed at the camera.
Center Radius:                  Center radius when aimed at the camera.
Number of points:               How many points the star has.
Fade (0..1):                    Intensity of flare when aimed at the
                                camera. (1 is transparant).
Radial fade (0..1):             Radially attenuates the flare to make it
                                less hard.
Edge Red, Green, Blue:          Color at edge of flare.
Star Radius 2:                  Outer radius at Max. Angle or higher.
Center Radius 2:                Inner radius at Max. Angle or higher.
Fade 2 (0..1):                  Flare intensity at Max. Angle or
                                higher (1 is transparant).
Max. Angle (0..180):            Angle with camera at wich the flare takes
                                on the second set of parameters.
