   Flags/methods for returning states.

   The SWIG conversion methods, as ConvertPtr, return an integer
   that tells if the conversion was successful or not. And if not,
   an error code can be returned (see swigerrors.swg for the codes).

   Use the following macros/flags to set or process the returning
   states.

   In old versions of SWIG, code such as the following was usually written:

     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
       // success code
     } else {
       //fail code
     }

   Now you can be more explicit:

    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
    if (SWIG_IsOK(res)) {
      // success code
    } else {
      // fail code
    }

   which is the same really, but now you can also do

    Type *ptr;
    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
    if (SWIG_IsOK(res)) {
      // success code
      if (SWIG_IsNewObj(res) {
        ...
	delete *ptr;
      } else {
        ...
      }
    } else {
      // fail code
    }

   I.e., now SWIG_ConvertPtr can return new objects and you can
   identify the case and take care of the deallocation. Of course that
   also requires SWIG_ConvertPtr to return new result values, such as

      int SWIG_ConvertPtr(obj, ptr,...) {
        if (<obj is ok>) {
          if (<need new object>) {
            *ptr = <ptr to new allocated object>;
            return SWIG_NEWOBJ;
          } else {
            *ptr = <ptr to old object>;
            return SWIG_OLDOBJ;
          }
        } else {
          return SWIG_BADOBJ;
        }
      }

   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
   SWIG errors code.

   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
   allows to return the 'cast rank', for example, if you have this

       int food(double)
       int fooi(int);

   and you call

      food(1)   // cast rank '1'  (1 -> 1.0)
      fooi(1)   // cast rank '0'

   just use the SWIG_AddCast()/SWIG_CheckState()

/* -----------------------------------------------------------------------------
 * Type initialization:
 * This problem is tough by the requirement that no dynamic
 * memory is used. Also, since swig_type_info structures store pointers to
 * swig_cast_info structures and swig_cast_info structures store pointers back
 * to swig_type_info structures, we need some lookup code at initialization.
 * The idea is that swig generates all the structures that are needed.
 * The runtime then collects these partially filled structures.
 * The SWIG_InitializeModule function takes these initial arrays out of
 * swig_module, and does all the lookup, filling in the swig_module.types
 * array with the correct data and linking the correct swig_cast_info
 * structures together.
 *
 * The generated swig_type_info structures are assigned staticly to an initial
 * array. We just loop through that array, and handle each type individually.
 * First we lookup if this type has been already loaded, and if so, use the
 * loaded structure instead of the generated one. Then we have to fill in the
 * cast linked list. The cast data is initially stored in something like a
 * two-dimensional array. Each row corresponds to a type (there are the same
 * number of rows as there are in the swig_type_initial array). Each entry in
 * a column is one of the swig_cast_info structures for that type.
 * The cast_initial array is actually an array of arrays, because each row has
 * a variable number of columns. So to actually build the cast linked list,
 * we find the array of casts associated with the type, and loop through it
 * adding the casts to the list. The one last trick we need to do is making
 * sure the type pointer in the swig_cast_info struct is correct.
 *
 * First off, we lookup the cast->type name to see if it is already loaded.
 * There are three cases to handle:
 *  1) If the cast->type has already been loaded AND the type we are adding
 *     casting info to has not been loaded (it is in this module), THEN we
 *     replace the cast->type pointer with the type pointer that has already
 *     been loaded.
 *  2) If BOTH types (the one we are adding casting info to, and the
 *     cast->type) are loaded, THEN the cast info has already been loaded by
 *     the previous module so we just ignore it.
 *  3) Finally, if cast->type has not already been loaded, then we add that
 *     swig_cast_info to the linked list (because the cast->type) pointer will
 *     be correct.
