xfwm: struts + multi monitor - does that work ?

Hello folks,


just looking at the geometry constraints code (that's also checking for
struts) and wonder whether that works at all - the implementation
doesn't care about monitors at all.

The netwm spec is a bit misleading at this point - since it predates the
Xinerama, it can't know about Xscreens spanning multiple monitors.
It says struts are in root window coordinates.

KWin seems to interpret the spec differently, assuming struts are
relative to monitors.

What can we do about that ?
