If a WebGL canvas is resized through the set_size function, we will re-create the painting surface. However, this currently leaks all of the associated EGL/OpenGL objects. This change introduces the free_surface_resources function which will free all resources associated with the painting surface. It will be called before allocating a new surface and during context destruction. It keeps track of the OpenGL texture for the color buffer in m_impl instead of just storing it on the stack.
