Bug description:

https://git.gnome.org/browse/metacity/tree/NEWS?h=3.18.5
[Impact]
Windows can not be moved above the top of screen because the coordinates
system used is wrong.
[Test Case]
* Launch a non-CSD application, such as Firefox or Thunderbird;
* Try Alt-dragging it above the top of the screen.
[Regression Potential]
The fix is changing the coordinates system to the right one and should not
cause any regressions.
-----------------------------------------------------------------------------
After upgrading to 15.10, I can no longer Alt-drag Firefox and
Thunderbird windows above the top of the screen. When I attempt to do
so, the window snaps downward along the y-axis so that the titlebar
aligns with top of screen. Other applications such as gnome-terminal
do not seem to be affected.
I ran git-bisect on metacity, and narrowed the regression down to this
