// This is a compromise between Gaussian Blur and Box blur

//
// 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

// or reduced by one, depending on if they are on the right or
// on the left side of the stack.
