* torus is ok but still need to solve my problem of normals. I think its a problem of overflow and i should transform unit normal coord in something a bit smaller but close to unit.
* strange artefacts appears on top screen(no-3D) with the torus ...i think its caused by the malloc...or a mistake i havn't seen. If somebody see something, I would be glad to know.
* added some other solids.
* codes of the exemple, and functions only file (to include in a lib for exemple) are provided.
