GNOME Bugzilla – Bug 705766
Last modified: 2013-08-13 14:40:40 UTC
GTK+ uses this property for CSD support so that shadows and invisible borders are not considered part of the actual window frame.

Review of attachment 251273 [details] [review]:
Seems to work mostly fine in my testing. One issue I could spot is that initial placement doesn't take the frame extents into account - the window gets placed 'floating' a short distance from the top left corner.
