/*----------------------------------------------------------
| OLD: slider
+-----------------------------------------------------------
| [1] REWRITE THIS:
| Right now [sa] can't get the position of an anchor tag!!!
| Rewrite the getPos function in the future.
| [2] FIX THIS:
| Right now horizontal scolling cannot be used!!!
| this is because if the page fits in the window and the target object
| is not flush left the horizontal scoll can never reach the end scroll!
| Right now ePos.x is always 0
+-----------------------------------------------------------
| FIXES: [08.04.07]
| This version has the following fixes for rebuild "news" display
| This is a hack and slash patch - should use "smoothScroll.js" but would be a bitch to integrate it into this old framework.
| + uri verification includes the query (search) parameters as well - previously it only verified the full pathname.
| + added scroll canceling
