+	* x11vnc: update classes/ssl jars, patches, and script. 
+	  update prepare_x11vnc_dist.sh to 0.9.13. Makefile.am no top_srcdir
+	  Allow user to set avahi name and port via env. vars.  Add
+	  avahi_timeout() sigalarm.  Rename pointer() to pointer_event()
+	  because Xdefs.h is included for some unknown reason. Add
+	  -always_inject option.  Add vnc_reflect_cursor_pos() for -reflect
+	  mode.  Attempt at libvncclient VeNCrypt (disabled.)  Fix bug
+	  with --with-system-libvncserver missing FinishedFrameBufferUpdate.
+	  More info in VncViewer.class http warning.  Look for gdm* in
+	  find display heuristics (e.g. gdm3).  More heuristics with
+	  XAUTHLOCALHOSTNAME attempts.  X11VNC_CREATE_MAX_DISPLAYS: let user
+	  specify max number of -create displays.  FD_USERPREFS modes for
+	  -unixpw (user conf file.) Document all exiting behavior.  Let

+                       VNC mouse event force the pointer to the indicated x,y
+                       position anyway.  Recent (2009) gui toolkits (gnome)
+                       have problems with x11vnc's original mouse input
+                       injection method.  So x11vnc's mouse input injection
+                       method has been modified.  To regain the OLD behavior
+                       use this option: -always_inject.  Then x11vnc will
+                       always force positioning the mouse to the x,y position
+                       even if that position has not changed since the previous
+                       VNC input event.
+
+                       The first place this problem was noticed was in gnome
+                       terminal: if you pressed and released mouse button 3, a
+                       menu was posted and then its first element 'New Terminal
+                       Window' was activated.  This was because x11vnc injected
+                       the mouse position twice: once on ButtonPress and again
+                       on ButtonRelease.  The toolkit interpreted the 2nd one
+                       as mouse motion even though the mouse hadn't moved.
+                       So now by default x11vnc tries to avoid injecting the
+                       2nd one.
+
+                       Note that with the new default x11vnc will be oblivious
+                       to applications moving the pointer (warping) or the
+                       user at the physical display moving it.  So it might,
+                       e.g., inject ButtonRelease at the wrong position.
+                       If this (or similar scenarios) causes problems in your
+                       environment, specify -always_inject for the old method.

+.IP
+The first place this problem was noticed was in gnome
+terminal: if you pressed and released mouse button 3, a
+menu was posted and then its first element 'New Terminal

+the mouse position twice: once on ButtonPress and again
