  GLDrawableFactory* [dummy|offscreen] Surface creation 
  w/ own device does _not_ require locking on global shared device.

  GLJPanel: Expose 'initializeBackend(boolean offthread)' allowing user 
  to trigger backend initialization eagerly and offthread (optional, !WINDOWS)

TestPerf001GLJPanelInit02AWT compares all variations: no-gl, glcanvas, gljpanel and gljpanel-initMT (offthread)
