N0NameN0 a46deda984 [DEL] in GRRLIB_3D.c All Light functions (uggly way to provide light imho)
[ADD] NEED_GRRLIB_FUNCTION a sample demo code that can be a base to code new functions !! i really need help on this !!

/*===========================================
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 effets in this demo.
With the help of the doc you can try also to find how it works,
for exemple i didnt succes fully coded a specular position and direction....
So i repeat i need HELP !!! ;)
