+===== Usage =====
+Altering the parameters will dinamically affect the result.
+Usage example:
+<code objc>
+SXRadialBlurFilter *filter = [SXRadialBlurFilter blurFilter];
+filter.blurCenterPosition = [SPPoint pointWithX:center.x y:center.y];
+filter.distance = 1;
+filter.strength = 2;
+displayObject.filter = filter;
+</code>

+=== Notes ===
+  * The filter is written with MRC; if you want to add this filter in an ARC-enabled project, follow [[http://jeffreysambells.com/2012/02/21/disable-arc-in-xcode-on-a-per-file-basis|these steps]] to selectively deactivate ARC for the radial blur filter.
+  * Use the ''marginX/Y'' property of the filter if it the effect is cut at the sides.
+  * Change the "blur" parameter to change the number of passes. More passes result in a smoother blur but also worse performances.
