/**
\todo
- Les coronas ne sont pas g<>er avec le nouveau systeme, seul le dynamic lighting l'est
- calculer l'offset des coronas au chargement du level et non faire la moyenne
au moment de l'afficher
BP: euh non en fait il faux encoder la position de la light dans le sprite
car c'est pas focement au mileux de plus il peut en y avoir plusieur (chandelier)
- changer la comparaison pour l'affichage des coronas (+ un epsilon)
BP: non non j'ai trouver mieux :) : lord du AddSprite tu rajoute aussi la coronas
dans la sprite list ! avec un z de epsilon (attention au ZCLIP_PLANE) et donc on
l'affiche en dernier histoir qu'il puisse etre cacher par d'autre sprite :)
Bon fait metre pas mal de code special dans hwr_project sprite mais sa vaux le
coup
- gerer dynamic et static : retenir le nombre de lightstatic et clearer toute les
light > lightstatic (les dynamique) et les lightmap correspondant dans les segs
puit refaire une passe avec le code si dessus mais rien que pour les dynamiques
(tres petite modification)
- finalement virer le hack splitscreen, il n'est plus necessaire !
