It seems arbitrary to make just this WebGLObject type non-copyable. Why not make
the base class, WebGLObject, non-copyable?

[Eric Willigers, 2016/09/01 06:02:26]

Done. I think I was looking at classes that held vectors. I missed
WebGLFramebuffer, which becomes non-copyable as it indirectly inherits from
WebGLObject.

 public:
     enum VaoType {
         VaoTypeDefault,
         VaoTypeUser,
     };
 
     ~WebGLVertexArrayObjectBase() override;
 
     GLuint object() const { return m_object; }
