Currently, scrolling to the far right or bottom of the ScrollPanel requires the user to access the scrollHeight property of the DOM element directly as followings:
setScrollPosition(DOM.getElementPropertyInt(getElement(), "scrollHeight"));

Fix:
Added the following convenience methods to abstract the DOM portion of the code:
scrollToTop()
scrollToBottom()
scrollToLeft()
scrollToRight()
Testing:
Manually verified the new methods scroll to the correct locations in all browsers.
