+earlier than 2.5.4, and for some complex window hierarchies it can reduce apparent refresh delays. You may
+still specify wxCLIP\_CHILDREN for individual windows.}

+\twocolitem{msw.staticbox.optimized-paint}{If set to 0, switches off optimized wxStaticBox painting.
+Setting this to 0 causes more flicker, but allows applications to paint graphics on the parent of a static box
+(the optimized refresh causes any such drawing to disappear).}
