this is the same thing as instance_place, but works in 3d.
plz critique it all over.

//
//    Usage:
//        i=d3d_instance_place(x,y,z,par_solid);
//
//  Arguments:
//      x
//      y
//      z
//      obj
//
//  Returns:
//      the id of the instance of type obj met when
//      the current instance is placed at position (x,y,z).
//      obj can be an object or the keyword all. If it
//      does not exist, the special object noone is returned.
//
