/************** PINT Rollover code v.91 **************
by James Brock
copyright PINT Inc. 2002
This rollover code is supposed to be
1. flexible, to accomodate all possible rollover activity
2. compatible, should work on anything better than IE4, Netscape 4
3. easy, so that all the rollover information can be inserted into the img tag in a simple way
4. robust, so that errors, typos, bad DOM support make it degrade gracefully
