starting in 3.10.0-beta1, InputManager.setCursorVisible() re-centers the cursor

[stephengold]

In 3.9.0-alpha4 and earlier builds of JME, invoking inputManager.setCursorVisible() has no effect on the position of the mouse cursor.

In 3.9.0-beta1 and 3.9.0-beta2, inputManager.setCursorVisible() causes the cursor to jump to the center of the window.

Here is a test app:

package mygame;

import com.jme3.app.SimpleApplication;
import com.jme3.input.KeyInput;
import com.jme3.input.controls.ActionListener;
import com.jme3.input.controls.KeyTrigger;
import com.jme3.input.controls.Trigger;

public class Main extends SimpleApplication implements ActionListener {

    public static void main(String[] args) {
        new Main().start();
    }

    @Override
    public void simpleInitApp() {
        // Configure the input mapping:
        Trigger tabTrigger = new KeyTrigger(KeyInput.KEY_TAB);
        String toggleAction = "toggle cursor";
        inputManager.addMapping(toggleAction, tabTrigger);
        inputManager.addListener(this, toggleAction);

        // Pressing the TAB key invokes this.onAction() below.
    }

    @Override
    public void onAction(String string, boolean isPressed, float tpf) {
        if (isPressed) { // toggle cursor visibility:
            boolean isVisible = inputManager.isCursorVisible();
            boolean makeVisible = !isVisible;
            inputManager.setCursorVisible(makeVisible);
        }
    }
}
