// Description: Performs menu button animation in the global navigation bar for the Consumer View Intellectual Property Site.
//
//              The navigation bar contains menu buttons for each of the main website sections.  These
//              functions animate the buttons when they are rolled over with the mouse.  They also highlight
//              the menu button for the section of the website the user is currently in.
//
//              There are two versions for each menu button.  The first is the ground (deactivated) state.
//              The second is the state the button takes on when it is rolled over by the mouse.  This state
//              is also used for the menu button in the active section of the website.
//
//              This JavaScript file has an associated JSP, JSPANavigation.jsp, which is included in the Site
//              Studio code fragment to which this file belongs.  The JSP drives the creation of the global
//              navigation menu bar.
//


//
// Define general variables.
//
var bookMark = "";
var prefix = (isSpanish ? "sp_" : "");


//
// Set menu button image variables.
