No, if they were graphics they would still be properly selectable, and if 
there was an `alt' attribute, its value would probably show up in the copied 
content.

Programming is based on logic, not mysticism.  If you do not know the 
answer, you should better do not answer at all instead of posting such 
superstitious nonsense.

In this case, first each word is being made the content of an invalid 
`cufontext' element within an invalid `cufon' element, and the `cufontext' 
elements are hidden by setting their width and height to 0, and their 
overflow to hidden.

Then the content of `cufontext' elements is being painted as paths on a 
`canvas' element that is the child of the corresponding `cufon' element 
each, using an ECMAScript implementation (e. g. JavaScript).

This is facilitated using the Cufon.replace(…) and Cufon.now() calls in 
lines 36 and 37 of the script resource, /js/index, included at line 514 of 
the main XHTML document.  The calls are part of YUI CUFON, as used in line 
44 of /page/-/cwa-union/js/source.js, which is included at line 513 of the 
main XHTML document.

Obviously this approach cannot be recommended.

Correct.

When all you know is jQuery, every problem looks $(olvable).
