I just manually applied the add-gtk-frame-extents-to-net-supported (one line, one file) to a
downloaded copy of current Ubuntu Xenial compiz-0.9.12.2+16.04.20151211, built fine, 
runs fine. Perhaps the previous confusion came from attempts to build the other branch
referenced in the bug report last summer, maybe of all the things I tried to do with 
0.9.12.1 I missed this one combination? Anyway, I've got it working here, gtk window
decorator and all, built against GTK 3.19.8 on top of all else.

Tested it with gnome-disks, compositing works fine and the rounded
corners work!
