+  Specifies whether to use or not damage optimizations with the openGL
+  rendering. Damage are drawable regions which are in need of
+  redisplay to repair the effects of window manipulation or to apply
+  data change. The value is a boolean that can have the values 0 or
+  1. The value 0 specifies that no optimization is applied, ie that
+  the whole area of our widget is redisplayed. A value of 1 asks for
+  damage optimization: TkZinc records an update area where the change

+  speed up redrawing in most cases but with some graphic cards it may
+  generate visual trails. The default value is {\tt 0}.
