/*===========================================

NoNameNo
|
|
Since I cant code all these new function alone,
|
|
I really need help to find the best way to provide
|
|
GRRLIB functions to all these new effects in this demo.
|
|
With the help of the doc you can try also to find how it works,
|
|
for example I didn't success fully coded a specular position and direction...
|
|
So I repeat I need HELP !!! ;)
