* Add loopback reference from rdman to the backend. This is only required when we need to acquire the tman for the animation. This is not a reasonable arrangement since the animation should be backend transparent. We should not touch the backend directly from the animation. We should relocate the tman to the rdman. * Remove reference to the MBApp from the mb_button_t so that it will be easier for us to generate button inside the sprite.
