/*
 *    QuickDraw 3D 1.5 Note:
 *
 *    Shapes and Sets are now (sort of) polymorphic.
 *
 *        You may call Q3Shape_Foo or Q3Set_Foo on a shape or a set.
 *        The following calls are identical, in implementation:
 *
 *            Q3Shape_GetElement            =    Q3Set_Get
 *            Q3Shape_AddElement            =    Q3Set_Add
 *            Q3Shape_ContainsElement        =    Q3Set_Contains
 *            Q3Shape_GetNextElementType    =    Q3Set_GetNextElementType
 *            Q3Shape_EmptyElements        =    Q3Set_Empty
 *            Q3Shape_ClearElement        =    Q3Set_Clear
 *
 *    All of these calls accept a shape or a set as their first parameter.
 *
 *    The Q3Shape_GetSet and Q3ShapeSetSet calls are implemented via a new
 *    element type kQ3ElementTypeSet. See the note above about
 *    kQ3ElementTypeSet;
 *
 *    It is important to note that the new Q3Shape_...Element... calls do not
 *    create a set on a shape and then add the element to it. This data is
 *    attached directly to the shape. Therefore, it is possible for an element
 *    to exist on a shape without a set existing on it as well.
 *
 *    In your application, if you attach an element to a shape like this:
 *        (this isn't checking for errors for simplicity)
 *
 *        set = Q3Set_New();
 *        Q3Set_AddElement(set, kMyElemType, &data);
 *        Q3Shape_SetSet(shape, set);
 *
 *    You should retrieve it in the same manner:
 *
 *        Q3Shape_GetSet(shape, &set);
 *        if (Q3Set_Contains(set, kMyElemType) == kTrue) {
 *            Q3Set_Get(set, kMyElemType, &data);
 *        }
 *
 *    Similarly, if you attach data to a shape with the new calls:
 *
 *        Q3Shape_AddElement(shape, kMyElemType, &data);
 *
 *    You should retrieve it in the same manner:
 *
 *        if (Q3Shape_ContainsElement(set, kMyElemType) == kTrue) {
 *            Q3Shape_GetElement(set, kMyElemType, &data);
 *        }
 *
 *    This really becomes an issue when dealing with version 1.0 and version 1.1
 *    metafiles.
 *
 *    When attempting to find a particular element on a shape, you should
 *    first check with Q3Shape_GetNextElementType or Q3Shape_GetElement, then,
 *    Q3Shape_GetSet(s, &set) (or Q3Shape_GetElement(s, kQ3ElementTypeSet, &set))
 *    and then Q3Shape_GetElement(set, ...).
 *
 *    In terms of implementation, Q3Shape_SetSet and Q3Shape_GetSet should only be
 *    used for sets of information that are shared among multiple shapes.
 *
 *    Q3Shape_AddElement, Q3Shape_GetElement, etc. calls should only be used
 *    for elements that are unique for a particular shape.
