When using OpenGL list, one must specify ids. This module can return unused ids when needed.
Here are also defined the common primitive for drawing, see
visu_gl_drawDistance()
for instance.
int
visu_gl_objectlist_new (int size
);
It returns the id that can be used to link glObjectList. This number is also added to the list of glObjectList to be displayed. The size parameter is the number of lists that could be used by the user for this glObjectList. Then the next call to this function will return the last value plus the size plus one.
void
visu_gl_objectlist_init (void
);
Used to initialise this part of code, don't use it.
