+ * Remove Class Filter Without Access to Class Object
+ *
+ * In order to use the core WordPress remove_filter() on a filter added with the callback
+ * to a class, you either have to have access to that class object, or it has to be a call
+ * to a static method.  This method allows you to remove filters with a callback to a class
+ * you don't have access to.

+ * @param string $class_name  Class name for the filter's callback
+ * @param string $method_name Method name for the filter's callback
+ * @param int    $priority    Priority of the filter (default 10)
+ *
+ * @return bool Whether the function is removed.
