Should we instead just use { Hovered, Pressed } ?

{ SpinUp } != { Hovered, Pressed }.

From RenderTheme::extractControlStatesForRenderer:

    if (isHovered(o)) {
        states.add(ControlStates::States::Hovered);
        if (isSpinUpButtonPartHovered(o))
            states.add(ControlStates::States::SpinUp);
    }
    if (isPressed(o)) {
        states.add(ControlStates::States::Pressed);
        if (isSpinUpButtonPartPressed(o))
            states.add(ControlStates::States::SpinUp);
    }
