Looks like it. I can only find one call site of `get_drawable_data()` (in [Java_sun_awt_X11_XRobotPeer_getRGBPixelsImpl()](https://github.com/openjdk/jdk/blob/8441d51e71e143250b44eea74114a624cf00cc3e/src/java.desktop/unix/native/libawt_xawt/awt/awt_Robot.c#L336)) and the `scale` parameter is always 1. I think I can drop it from the interface if you prefer.
