Prototype void object_add_surface_head(ACObject *ob, Surface *p);

will add it to the start of the list - very fast. (the order of the surfacelist is generally unimportant)

If you already have a list of surfaces, use this:

Prototype void object_add_surfaces(ACObject *ob, List *l);

(this simply calls object_add_surface_head for each item on the list).

the _head functions will always be faster.

Remember that vertices can't be shared across ACObjects.
