[FX 9680] GrayscaleLib

[Eiyeron Profile]

Hello everyone!
I'm almost finished it, but I will need some help into debuggin that mass of work: a full functionnal grayscale engine with graphicals functions!
It's the very port of MonochromeLib from PierrotLL, but for grayscale.
The engine is made to be rebootless, the core works, I use it, but for the graphicals functions, I don't really know, and that's why I need your help!

Right, for the sprites, you need a char containing first light layer, then dark_layer, then (optionally) Alpha layer, and use flags for the sprites routines.
