VolatileImage buffer disabled by default for not signed web apps !?

 Hi,

 Pivot 2.0 introduced the 'disableVolatileBuffer' flag (PIVOT-390). Its 
 default value is true. In case of not signed web apps (JWS, Applet) a 
 SecurityException will be thrown (and catched) and the default value 
 remains unchanged: true. So, these apps will never benefit from the 
 faster VolatileImage buffer. Did I overlook something?

 public abstract class ApplicationContext {

   public static class DisplayHost extends java.awt.Component {

     private boolean disableVolatileBuffer = true;

     public DisplayHost() {
       ...
       try {
         disableVolatileBuffer = 
 Boolean.parseBoolean(System.getProperty("org.apache.pivot.wtk.disablevolatilebuffer"));
       } catch (SecurityException ex) {
         // No-op
       }
       ...
     }
   }
 }

Thanks for catching that. The default should be false.
