commit dcdbe5e9bd7dcdb461b48cd0ab9eb72c6010594f
Author: Cosimo Cecchi <cosimoc gnome org>
Date: Fri Mar 2 19:18:26 2012 -0500
notification: import GtkNotification from gnome-contacts
Rename it to GdNotification for compatibility with our namespace.
Also there's a few enhancements:
- improve and refactor size requests
- turn timeout into an int, and use -1 to signal to never expire
- add a show-close-button property that can be used to hide the
automatic close button, and let children provide theirs
