Decoration buttons do not follow custom specified layout in desktop environment

Some desktop environments (like Plasma) allow to specify the layout of window decoration buttons. GTK+ applications do not honor these settings, making them being the odd spot when the general close button is on the left.
Steps to reproduce:
- Run Plasma session
- Configure window decoration to have close button on the left
- Start gtk3-demo
Actual Result: close button is on the right
Expected Result: close button is on the left
See the attached screenshot highlighting the issue using the double decorated on non-compositing bug (see bug 729769).
