. Tested GCX scene loading
. Upgraded primitives to take additional vertex streams from other primitives
. Fixed wrong normal map when using only white textures
. Fixed bad multiple vertex streams aggregation
 => Can now draw informations from multiple vertex buffers
. Got crazy and refactored NjFloatXXX by what I originally intended to do: same names as in shaders!
 => Actually, I've been forced to prefix the math lib by NjSomething because it has been used by Ubi at some point and they didn't want any conflict with anything else (and they didn't like namespaces)
