Button animations on MPRIS control

There is no button animation when receiving playback control input from MPRIS

With a mouse, the animation is on mouse down and mouse up. With a touchpad in tap-to-click mode these are not different events. Likewise when using the MPRIS controls, there is no mouse signal. A predefined animation sequence could be used, but it feels laggy.
