Inserts a new item at the end of the list.
HRESULT appendItem( ISVGTransform *newItem, ISVGTransform **ppResult );
- [in] The item to insert. The first item is number 0.
- [out, retval] The inserted item.
Returns S_OK if successful, or an error value otherwise.
If the newItem item is already in the list, the ISVGPointList::appendItem method removes the item from its previous list before inserting it into this list. The inserted item is the item itself and not a copy.
