A custom image representation of the mouse cursor. On platforms that don't
support custom cursors, Cursor.DEFAULT will be used in place of the
specified ImageCursor.
Example:
import javafx.scene.*;
import javafx.scene.image.*;
Image image = new Image("mycursor.png");
Scene scene = new Scene(400, 300);
scene.setCursor(new ImageCursor(image,
image.getWidth() / 2,
image.getHeight() /2));
