/**
 * An options panel that can be added to an
 * <code>org.fife.ui.OptionsDialog</code> to display options appropriate for an
 * <code>RSyntaxTextArea</code>.  This panel allows the user to change the
 * following properties of the text area:
 * <ul>
 *    <li>Syntax highlighting colors</li>
 *    <li>Bracket matching and color</li>
 *    <li>Toggle whitespace (spaces and tabs) visibility</li>
 *    <li>Toggle anti-aliasing and fractional fontmetrics</li>
 * </ul>
 * It also gives the user a button to restore the default color scheme.
