Bug 1434565 - Put some meanigful timestamp to nsRemoteService::HandleCommandLine(), r?jhorak We need to put a timestamp to nsRemoteService::HandleCommandLine() to allow Gtk+ focus opened Firefox window. Unfortunately we don't have much choice how to get the timestamp at DBUS remote service so ask for gtk_get_current_event_time() and when GDK_CURRENT_TIME is returned (it means we don't have the timestamp) use g_get_monotonic_time() as well as at nsWindow::GetEventTimeStamp().

 * This class allows access to Android's direct texturing mechanism. Locking
 * the buffer gives you a pointer you can read/write to directly. It is fully
 * threadsafe, but you probably really want to use the AndroidDirectTexture
 * class which will handle double buffering.
 * In order to use the buffer in OpenGL, just call Bind() and it will attach
 * to whatever texture is bound to GL_TEXTURE_2D.
