 void DeleteSurface(void)
 {
  if(m_eglSurface != EGL_NO_SURFACE)
  {
   glFlush();
   eglMakeCurrent(m_eglDisplay ,EGL_NO_SURFACE ,EGL_NO_SURFACE , EGL_NO_CONTEXT);
   eglDestroySurface(m_eglDisplay,m_eglSurface);
   m_eglSurface = EGL_NO_SURFACE;
  }
 }


 void ResetSurface(void)
 {
  if(m_eglSurface == EGL_NO_SURFACE)
  {
   m_eglSurface = eglCreateWindowSurface(m_eglDisplay,m_eglConfig , m_nativeWindowType , NULL);
   eglMakeCurrent(m_eglDisplay ,m_eglSurface ,m_eglSurface , m_eglContext);
  }
 }
