    screenshot-window-sizer: Rearrange calculation
    
    eslint has a rule to prohibit unnecessary parentheses. While this is
    generally a good idea stylistically, the parentheses in a calculation
    of (a / b) * c add more clarity, as a / b * c lacks the unambiguity of
    proper math notation:
    
       a                a
      --- * c   vs   -------
       b              b * c
    
    We can still follow the style rule by rearranging to the unambiguous
    c * a / b.
