  # Creates a slide and scale visual state block that gives an experience

  slide_and_scale: MMDrawerVisualState.slideAndScaleVisualStateBlock,

  # Creates a slide visual state block that gives the user an experience that
  # slides at the same speed of the center view controller during animation.
  # This is equal to calling parallaxVisualStateBlockWithParallaxFactor: with
  # a parallax factor of 1.0. This is similar to the menu in Spotify's app.
  slide: MMDrawerVisualState.slideVisualStateBlock,

  # Creates a parallax experience that slides the side drawer view controller
  # at a different rate than the center view controller during animation. For
  # every parallaxFactor of points moved by the center view controller, the side
  # drawer view controller will move 1 point. Passing in 1.0 is the equivalent
  # of a applying a sliding animation, while passing in 'MAX_FLOAT' is the equivalent
  # of having no animation at all.
  parallax: MMDrawerVisualState.parallaxVisualStateBlockWithParallaxFactor(3),

  # Creates a swinging door visual state block that gives the user an experience that
  # animates the drawer in along the hinge.
