    screenShield: Tweak curtain animation timings
    
    Rationale:
     - Getting something out of the way should be quick;
    
     - Very few things in the real world move linearly so, linear
       animations, especially for something as big and visible as this,
       felt too artificial;
    
     - Moving the curtain out should start slower to make it feel like
       having weight (it fills the whole screen after all) but quickly
       accelerate towards the end to make it snappy too.
