 * scrollbars).  Rules for everything else related to XUL can be found in
 * xul.css.  (This split of the XUL rules is to minimize memory use and improve
 * performance in HTML/SVG documents.)

 * This file should also not contain any app specific styling.  Defaults for
 * widgets of a particular application should be in that application's style
 * sheet.  For example style definitions for navigator can be found in
