*
* We can't test for this because it depends on whether the

*
* We also use this variable as a guard against a second
* independent bug with transformed repeating pictures:
*
* http://lists.freedesktop.org/archives/cairo/2004-September/001839.html
*
* Both are fixed in xorg >= 6.9 and hopefully in > 6.8.2, so
