nit: alignment?

I remove this for now since I have not find a reason to call
EGLExt.eglPresentationTimeANDROID. I asked the hangouts folks about when
EGLExt.eglPresentationTimeANDROID is needed. (it requires EGL14 so I would like
to do it in a follow up cl if it is required. We then must use EGL14 on some SDK
versions and EGL10 on others) 

+    EGLExt.eglPresentationTimeANDROID(eglDisplay, eglSurface, timeStampNs);
+    EGL14.eglSwapBuffers(eglDisplay, eglSurface);
+  }
+
   // Return an EGLDisplay, or die trying.
   private static EGLDisplay getEglDisplay() {
     EGLDisplay eglDisplay = EGL14.eglGetDisplay(EGL14.EGL_DEFAULT_DISPLAY);
