* le calcul des valeurs des vertex départ/arrivée des lignes
|
||||
* et l'allocation du buffer lignes (! LIGNES ! <> pas vertex)
|
||||
* soit fait par des realloc(),

* et non, comme actuellement, en une seule fois lors de l'initialisation

|

*
|

* Cette restructuration sera plus lisible si le code qui décrit les flèches
|
||||
* est nettement séparé de celui qui décrit l'espace.
|

*
|

* Certaines fonctions des actuels fichiers '/graphics' et '/buffers'

* La fonction draw_line(a,b) sera utilisée pour tracer toutes les lignes
|

* (qu'elles décrivent l'espace ou les flèches).
|

* Elle calcule les adresses mémoire des vertex (a) et (b)
