//
// Image Rollover Support
//
//  Make a construct like:
//  <a href="xyz" class="rollover"><img src="imageoff.gif" /></a>
//
//  Then make sure images named "imageoff.gif" and "imageon.gif" exist.  
//  You're done. (works with any file extension).
//
//  Based on Langridge p. 34, but fixed to work with multiple child nodes
//  of the <a>.
//

// From an event handler, get the Anchor element in which the event occurred.
