An important mesa fix

[Matthias Clasen <matthias clasen gmail com>]

Hi fellow distributors,


we've noticed a regresssion in taking screenshots with the gnome-shell
calendar popup open (
https://bugzilla.gnome.org/show_bug.cgi?id=744978 ). This turned out
to be caused by a bug in mesa that has been fixed in the meantime. You
might want to make sure that your mesa build includes the patch in
http://lists.freedesktop.org/archives/mesa-dev/2015-February/078074.html
