+ * describe more sophisticated Ops such as ones that take multiple sources.
+ * Each class implementing this interface will specify whether or not it
+ * will allow an in-place filtering operation (i.e. source object equal
+ * to the destination object). Note that the restriction to single-input
+ * operations means that the values of destination pixels prior to the
+ * operation are not used as input to the filter operation.
