      // It creates much better looking blurs than Box Blur, but is
      // 7x faster than my Gaussian Blur implementation.
      //
      // I called it Stack Blur because this describes best how this
      // filter works internally: it creates a kind of moving stack
      // of colors whilst scanning through the image. Thereby it
      // just has to add one new block of color to the right side
      // of the stack and remove the leftmost color. The remaining
      // colors on the topmost layer of the stack are either added on
      // or reduced by one, depending on if they are on the right or
      // on the left side of the stack.
