/* Bug history
*
* 2005-04-12 Carl Worth <cworth@cworth.org>
*
* I noticed that if we call cairo_select_font_face, but then do a
* cairo_destroy before ever drawing any text, then we get:
*
* *** glibc detected *** double free or corruption (fasttop): 0x083274d0 ***
* Aborted
*
* 2005-04-14 Owen Taylor <otaylor@redhat.com>
*
* Fixed... just a stray free().
