Merge branch 'master' of ssh://gitlab.version.fz-juelich.de:10022/vis/xdg_profiles

TODO

 ToDo:
 * "vncserver -profile" darf nur Profile in ${XDG_PROFILES_DIR} anzeigen, welche nicht 'hidden' sind.
-* call /etc/bashrc in xdg_profile_set.sh, weil manche User eine sehr sehr alte bashrc haben und diese kein Update bekommt.
 * link gtk-bookmarks to ${XDG_CONFIG_HOME}/gtk-3.0/bookmarks
 * merge ${XDG_CONFIG_DIRS}/gtk-3.0/bookmarks in ${XDG_CONFIG_HOME}/gtk-3.0/bookmarks
 * add places $WORK und $ARCH in ${XDG_PROFILES_DIR}/default/gtk-3.0/bookmarks
-* have default-module for ParaView
-* adjust icon positions on desktop
-* change Llview icon
-* Terminal-Nachrichten an User anzeigen (write, wall)
-   - Idee: 1) xterm versteckt (devilspie2) laufen lassen und dort 'screen -L' starten
-             (screen muss zwingend im Vordergrund laufen, damit Nachrichten auch im Log landen)
-           2) mit anderem Script das modify-date und file-size der Logdatei pollen
-             wenn: Größe > 0 und letzte Änderung länger als 1 Sekunde vergangen
-                (Zeitversatz um 1sec: wollen verhindern, dass Nachrichten abgegriffen werden, bevor sie komplett ins Log geschrieben wurden)
-             dann: Inhalt der Logdatei anzeigen und Logdatei leeren/löschen.

+  enable "-interframe"
+        Passing an argument of -noreverse to vncserver will disable the ability to make outbound (reverse) connections from the TurboVNC Server session.
+        If the no-reverse-connections directive is set in the TurboVNC security configuration file,
+        then that has the effect of enabling the -noreverse option for all new TurboVNC sessions that are started on the machine.
+
+        For these reasons, interframe comparison is not enabled by default and should not generally be enabled
+        except on bandwidth-constrained networks and with applications for which it can be shown to be beneficial.
+        Interframe comparison can be enabled by either passing an argument of -interframe to vncserver when starting a TurboVNC Server session
+        or by requesting a compression level of 5 or higher from the viewer (see below.)
+
+  lossless refresh
+        To perform a lossless refresh, press CTRL-ALT-SHIFT-L or click on the Lossless Refresh toolbar icon.
+  ALR behavior
+        You can override the default ALR behavior, thus making all screen regions eligible for ALR,
+        by setting the TVNC_ALRALL environment variable to 1 on the TurboVNC server machine prior to starting a TurboVNC session.
+        You can also set TVNC_ALRCOPYRECT to 0 to make CopyRect regions ALR-ineligible, which approximates the behavior of TurboVNC 1.2.1 and prior.
