TurboVNC Support:
----------------
TurboVNC is supported in an experimental way. To it build via the
build.unix script described in the next section, do something like:
env TURBOVNC='-L/DIR -Xlinker --rpath=/DIR -lturbojpeg' ./build.unix
where you replace /DIR with the directory where the libturbojpeg.so
(http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=166100)
is installed.
You may not need to set rpath if libturbojpeg.so is installed in a
standard location or you use LD_LIBRARY_PATH to point to it.
See the turbovnc/README in the vnc_unixsrc/vncviewer directory for
more info. You can find it in the ssvnc source tarball and also
in:
src/zips/vnc_unixsrc_vncviewer.patched.tar
More TurboVNC features will be enabled in the future.

If available on your platform, use a ssvncviewer compiled with
TurboVNC support. This is based on the the VirtualGL project:
http://www.sourceforge.net/projects/virtualgl You will need
to install the VirtualGL's TurboJPEG library too.
Currently (May/2009) only Linux.i686, Linux.x86_64, and
Darwin.i386 have vncviewer.turbovnc binaries shipped in the
ssvnc bundles. See the build instructions for how you might
compile your own.
Send CLIPBOARD not PRIMARY:
When sending locally selected text to the VNC server side,
send the CLIPBOARD selection instead of the PRIMARY selection.
Send Selection Every time:
Send selected text to the VNC server side every time the mouse
focus enters the main VNC Viewer window instead only when it
appears to have changed since the last send.

Use viewer-side (i.e. local) scaling of the VNC screen. Supply
