Bug#1026884: xfwm4: Reserved space through _NET_WM_STRUT property ignored

[Sébastien Dufromentel <elzen@fadrienn.irlnc.org>]

Package: xfwm4
Version: 4.18.0-1
Severity: normal
X-Debbugs-Cc: elzen@fadrienn.irlnc.org

Dear Maintainer,

Normally, windows like docks and panels can reserve some space on the screen
borders by using the X property _NET_WM_STRUT. It allow them to not be covered
by maximized windows, so they're always available visually and for mouse
action.

Since the 4.18, it looks like Xfwm ignore such property: when I maximize some
windows, they take the whole screen size and thus cover those reserved spaces,
which is a bit problematic. The other WM I have on this computer, Compiz and
Sawfish, still reserve space perfectly. I rollbacked to 4.16 using the bullseye
package, and it works again too, so it looks like something very specific to
this version of this particular WM.
