   Pb: THMapStorage is kind of a class
   THLab_()... comment je m'en sors?

   en template, faudrait que je les instancie toutes!!! oh boy!
   Et comment je sais que c'est pour Cuda? Le type float est le meme dans les <>

   au bout du compte, ca serait sur des pointeurs float/double... etc... = facile.
