Comment 7 for bug 735937

There is an (old) interesting discussion at http://mail.gnome.org/archives/wm-spec-list/2004-March/msg00007.html, but unfortunately it doesn’t seem to have led to any useful addition to the EWMH specification.

According to the specification:

« The Window Manager SHOULD calculate this space by taking the current page minus space occupied by dock and panel windows, as indicated by the _NET_WM_STRUT or _NET_WM_STRUT_PARTIAL properties set on client windows. »

We can probably write a similar implementation that will calculate the work area on one given screen, by subtracting from the screen geometry all the strut-reserved areas of all windows on this screen.
