Theme files from Google CDN?

Hi all,
very simple question but hard to find answer for me. How to rewrite
other jQuery UI files paths to use Google CDN?
What is path for e.g. "css/smoothness/jquery-ui-1.7.1.css" from CDN?
Page http://code.google.com/intl/cs/apis/ajaxlibs/documentation/index.html#jqueryUI
writes only about jQuery[.min].js and jquery-ui[.min].js.... But no
mention about themes files and so on.
