 * 
 * <h3>Screenshot</h3>
 * <p>The following screenshot is taken from the HelloControlsFX sample application,
 * and shows a normal TextField, with a {@link TextFields#createClearableTextField() clearable text field},
 * followed by three CustomTextFields. Note what happens with long text input - 
 * it is prevented from going beneath the left and right graphics. Of course, if 
 * the keyboard caret moves to the right, the text will become visible, but this
 * is because it will all scroll to the left (as is the case in a normal {@link TextField}).
