+    //
+    // I called it Stack Blur because this describes best how this

+    // 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.
