"unsigned" makes me nervous.  please use uint32_t from cstdint instead, unless
the size of this needs to be architecture-dependent for some reason (didn't seem
to be the case from the pages i found)

GLuint is actually defined as an unsigned, but I still change to uint32_t.

 
   bool has_alpha() const { return has_alpha_; }
   void set_has_alpha(bool has_alpha) { has_alpha_ = has_alpha; }
   virtual void Refresh() {}
 
  protected:
   // TextureData is not allowed to be instantiated.
   TextureData() : texture_(0), has_alpha_(true) {}
-  void set_texture(GLuint texture) { texture_ = texture; }
-  const GLuint* texture_ptr() { return &texture_; }
+  void set_texture(unsigned texture) { texture_ = texture; }
+  const unsigned* texture_ptr() { return &texture_; }
 
  private:
-  GLuint texture_;
+  unsigned texture_;
   bool has_alpha_;
   DISALLOW_COPY_AND_ASSIGN(TextureData);
 };
