+    // Java Author: Mario Klingemann <mario at quasimondo.com>
+    // http://incubator.quasimondo.com
+    // created Feburary 29, 2004

+    // This is a compromise between Gaussian Blur and Box blur
+    // 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.
+    //
+    // If you are using this algorithm in your code please add
