Fix for Bug #452 WindowsWGLGraphicsConfiguration.create(..) -> WindowsWGLGraphicsConfiguration.createFromCurrent(..) emphasizing that all resources are 'current' ie locked and available. This method is used for the external context/drawable creation only, called while they are current. Hence this method no more makeCurrent/release, which interfered with the current external context state.
WindowsWGLGraphicsConfigurationFactory: Move surface locking to the right (common) place.
