This is so silly, we should add a template for the RefPtr'ed Vectors in
RenderStyle.

+public:
+    static PassRefPtr<AppliedTextDecorationList> create() { return adoptRef(new AppliedTextDecorationList); }
+    PassRefPtr<AppliedTextDecorationList> copy() { return adoptRef(new AppliedTextDecorationList(*this)); }
+
+    const AppliedTextDecoration& operator[](int i) const { return m_vector[i]; }
+    AppliedTextDecoration& operator[](int i) { return m_vector[i]; }
+    const AppliedTextDecoration& at(size_t i) const { return m_vector.at(i); }
+    AppliedTextDecoration& at(size_t i) { return m_vector.at(i); }
+
+    bool operator==(const AppliedTextDecorationList& o) const { return m_vector == o.m_vector; }
+    bool operator!=(const AppliedTextDecorationList& o) const { return m_vector != o.m_vector; }
+
+    size_t size() const { return m_vector.size(); }
+    void append(const AppliedTextDecoration& decoration) { m_vector.append(decoration); }
+
+private:
+    Vector<AppliedTextDecoration, 1> m_vector;
+    AppliedTextDecorationList() { }
+    AppliedTextDecorationList(const AppliedTextDecorationList& o) : m_vector(o.m_vector) { }
