* Xext: use $USRDATADIR/SecurityPolicyUlrich Sibiller2021-01-181-3/+2
| | | | | | | | This reflects the path where the file is placed after installation. It also obsoletes the NX_ALTERNATIVEPOLICYFILE. Fixes ArcticaProject/nx-libs#988

* Window.c: suppress warningUlrich Sibiller2021-01-161-1/+1
| | | | | | | | This used to be printed only in TEST mode. Some while ago I had changed that to WARNING (because it is a warning...). However, this happens e.g. when running the xscreensaver vfeedback module and it does not look like it is a problem at all. So let's suppress this warning again and leave it to the TEST mode as it used to be.
