GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307,
USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

VNC 4.0 Source Distribution for Unix platforms
==============================================
Copyright (C) 2002-2004 RealVNC Ltd. All Rights Reserved.
This software is distributed under the GNU General Public Licence as published
by the Free Software Foundation. See the file LICENCE.TXT for the conditions
under which this software is made available. VNC also contains code from other
sources. See the Acknowledgements section below, and the individual files for
details of the conditions under which they are made available.
There are six programs here:
vncviewer - this is the VNC viewer, or client, program for X.
Xvnc - this is the X VNC server - it is both a VNC server and an X server
with a "virtual" framebuffer. You normally use the vncserver script
to start Xvnc.
vncserver - this is a wrapper script which makes starting an X VNC server
(i.e. desktop) more convenient. It is written in Perl, so to use
the script you need that.
vncpasswd - this program allows you to change the password used to access
your X VNC desktops. The vncserver script uses this program when
you first start a VNC server.
vncconfig - this program is used to configure and control a running instance
of Xvnc.
x0vncserver - this is an inefficient VNC server which continuously polls any
X display, allowing it to be controlled via VNC. It is
intended mainly as a demonstration of a simple VNC server.
In addition to these standalone programs, this distribution can also be used to
turn the native X server for a platform into a VNC server. For XFree86 version
4 servers, this is done using a module loaded at run-time. For other X servers
it requires replacing the native X server binary.
To build this distribution you need a C++ compiler as well as a C compiler.
You also need a reasonably recent version of the X window system installed.
This comes as standard with most unix machines. If you don't have it
installed, see http://www.xfree86.org or http://www.x.org
To build everything but Xvnc, do:
% ./configure
% make
This should build first some libraries - zlib, rdr, network, Xregion, rfb and
tx - then vncviewer, vncconfig and vncpasswd. If you already have zlib
installed on your system you can run "./configure --with-installed-zlib" if you
prefer (this is strongly advised on FreeBSD, since we've been told there are
problems otherwise).
Building Xvnc
=============
Building Xvnc and the VNC support for native X servers is much more complex.
If you don't need to build it, skip to the section below on installing.
Xvnc differs from the other programs in that it is built inside the X source
tree. Unlike previous versions of Xvnc, we do not provide an X source tree
with this distribution. We have designed the distribution to be as independent
as possible of the X tree used.
We have successfully used XFree86 version 4.3.0, 4.2.0 and 3.3.6 (available
from http://www.xfree86.org). You could also try the original X.org tree
available from http://www.x.org but this does not build as easily because of
lack of support for C++, no support for building server only, and other issues.
Note that the X tree is enormous and notoriously difficult to deal with -
building it is not for the faint-hearted!
Once you have a copy of the X source tree, make sure it is unpacked at the top
level of this distribution, so that the xc directory of the X source tree
matches the xc of this distribution, for example:
% tar xzf X420src-1.tgz
Then you must apply a patch to some files in the X source tree:
% patch -Np0 <xc.patch
If this works, you should be able to build the entire X tree, including Xvnc:
% cd xc
% make World
This will take a long time, and will quite probably fail for one reason or
another! If you are having trouble, we suggest you try to build the X tree in
isolation first before attempting it with the VNC additions.
If successful, in the xc/programs/Xserver directory you should find an Xvnc
binary, plus the native X server binary(ies) for your platform with VNC support
compiled in. If you are building from an XFree86 version 4 tree on a supported
platform, you should also find a vnc.so module in
xc/programs/Xserver/vnc/modules.
Exactly which X extensions and features are built into Xvnc and the native X
server binary is determined by the settings in xc/config/cf. The file vnc.def
contains the settings we use to build our binary distributions. You may need
to edit this and the other files as appropriate.
Installing
==========
Different unix platforms have different conventions for where software should
be installed. To copy the programs to some directory which is in your PATH
environment variable, such as /usr/local/bin, there is a script called
vncinstall which you can use:
% cd ..
% ./vncinstall /usr/local/bin
This will also attempt to install the manual pages in an appropriate directory.
You can specify an alternative directory as a second argument to vncinstall:
% ./vncinstall /usr/local/bin /usr/local/man
It will also try to install the vnc.so XFree86 version 4 module if appropriate.
This will be copied to the /usr/X11R6/lib/modules/extensions directory and can
be enabled like any other module by adding a Load "vnc" line to the Module
section of XF86Config. The parameters listed in the Xvnc manual page can be
set as options in XF86Config e.g. Option "passwordFile" "/root/.vnc/passwd".
Note that for some reason options cannot be set in the Module section of
XF86Config - try the Screen section.
If you want to use the Java VNC viewer, you should copy the files from
the java directory to some suitable installation directory such as
/usr/local/vnc/classes:
% mkdir -p /usr/local/vnc/classes
% cp java/* /usr/local/vnc/classes
We recommend that you use the vncserver script to run Xvnc for you. You can
edit the script as appropriate for your site. Things you may need to change
include:
* The location of Perl - if Perl is not installed in /usr/bin you'll need
to edit the "#!/usr/bin/perl" first line of vncserver.
* Xvnc's font path and color database. If you have an installation of
X which is not in the standard place you may need to add arguments to the
Xvnc command line to set these. These should be appended to the $cmd
variable at the comment "# Add font path and color database...".
* $vncJavaFiles - this specifies the location of the files for
the VNC viewer Java applet. The default is /usr/local/vnc/classes.

I have managed to build Xvnc on HPUX but only with some ugly hacking of
the X tree. The X tree I used as the basis for the build is the XFree86 4.2.0
tree. The XFree86 4.3.0 tree is unsuitable as it seems to have had some HPUX
stuff removed from it. I built using the aCC C++ compiler.
Set the following environment variables:
% CXX=/opt/aCC/bin/aCC
% CFLAGS="+DAportable"
% CXXFLAGS="+DAportable -AA +W749 +W740"
% BOOTSTRAPCFLAGS=-Dhpux
% export CXX CFLAGS CXXFLAGS BOOTSTRAPCFLAGS
Build the main part of the VNC distribution as normal:
% ./configure
% make
Unpack the X tree and apply the patches in xc.patch:
% gunzip -c X420src-1.tgz | tar xf -
% patch -Np0 <xc.patch
Then additionally apply the patches in hpux.patch:
% patch -Np0 <hpux.patch
Finally try building the X tree:
% cd xc
% make World
If it all goes to plan you will be left with Xvnc in xc/programs/Xserver. You
will probably have to modify the vncserver script to set up a sensible font
path, since many of the font directories on HPUX are different from the
defaults compiled into Xvnc.
If anyone can find a neater way of building a VNC-compatible X tree on HPUX
please let us know (see http://www.realvnc.com for contact details).

VNC 4 Source Distribution for Windows platforms
=============================================
VNC 4 is Copyright RealVNC Ltd. 2002-2004. This software is
distributed under the GNU General Public Licence as published by the
Free Software Foundation. See the accompanying licence.txt file for
the conditions under which the software is made available.
VNC 4 also contains code from other sources. See the Acknowledgements
section below, and the individual files for details of the conditions
under which they are made available.
The source tree contains a number of directories, and is most easily
built by loading the VNC workspace file (vnc.dsw) into Microsoft
Visual Studio 6/7. This will preserve the required dependencies
between the sub-projects.
There are three main executable projects:
vncviewer - The VNC Viewer for Win32.
winvnc - The VNC Server for Win32 (command-line operation
only).
vncconfig - The configuration applet and GUI front-end for VNC
Server.
These projects are designed to be built using Microsoft Visual C++
6.0, and should also compile with Microsoft Visual Studio .NET
(version 7). Other compilers have not been tested but the code base
is extremely portable.

VNC 4 Binary Distribution for Windows platforms
=============================================
VNC 4 is Copyright RealVNC Ltd. 2002-2004. This software is
distributed under the GNU General Public Licence as published by the
Free Software Foundation. VNC also contains code from other sources,
as outlined in the Acknowledgements section below.
The installer package contains two VNC components:
VNC Viewer - this is the VNC Viewer, or client, program for
Win32.
[Win9x, WinME, NT4, Win2000, WinXP,
Windows 2003 Server]
VNC Server - this is the VNC Server for Win32. It allows a
Windows desktop to be accessed remotely using a
VNC Viewer.
[Win9x, WinME, NT4, Win2000, WinXP(*),
Windows 2003 Server]
(*) May not work if the in-built Fast User Switching or Remote
Administration features are in use.

# C / C++ header dependency stuff
#
# Needs GNU make and vncmkdepend, a hacked version of makedepend
.SUFFIXES: .d
CMAKEDEPEND = vncmkdepend
CXXMAKEDEPEND = vncmkdepend
#
# The recommended method of doing dependency analysis in the GNU make manual
# turns out to be painfully slow. This method is similar but it's
# substantially faster and retains the desirable property that the user doesn't
# need to manually invoke a "make depend" step.
#
# As with the method described in the manual, we generate a separate dependency
# (.d) file for each source file. The .d file records the header files that
# each C or C++ source file includes. Any source file recorded in SRCS or
# CXXSRCS will cause us to try and include the corresponding .d file and GNU
# make then treats each .d file as a target to be remade.
#
# Unlike the manual's method, the rule we provide for making the .d file is
# actually a fake. All it does is record in a temporary file that the .d file
# needs to be remade. But as well as all the .d files, we also try to include
# a file called "depend.phony". This file never exists, but it causes GNU make
# to try and make the target "depend.phony". The rule for depend.phony then
# looks at the temporary files generated by the .d rules and then invokes the
# "omkdepend" program on all of the source files in one go.
#
#
# We use simple assignment here to remove any of the depend.tmp files
# at the time make parses this bit.
#
dummyvariable := $(shell $(RM) cdepend.tmp cxxdepend.tmp)
#
# Now the "fake" rules for generating .d files.
#
%.d: %.c
@echo "$<" >> cdepend.tmp
%.d: %.cxx
@echo "$<" >> cxxdepend.tmp
#
# The depend.phony rule which actually runs omkdepend.
#
depend.phony:
@if [ -f cdepend.tmp ]; then \
echo $(CMAKEDEPEND) $(ALL_CPPFLAGS) `cat cdepend.tmp`; \
$(CMAKEDEPEND) $(ALL_CPPFLAGS) `cat cdepend.tmp`; \
rm -f cdepend.tmp; \
fi; \
if [ -f cxxdepend.tmp ]; then \
echo $(CXXMAKEDEPEND) $(ALL_CPPFLAGS) `cat cxxdepend.tmp`; \
$(CXXMAKEDEPEND) $(ALL_CPPFLAGS) `cat cxxdepend.tmp`; \
rm -f cxxdepend.tmp; \
fi
#
# Now include the .d files and the "depend.phony" file which never exists.
# For some reason GNU make evaluates the targets in reverse order, so we need
# to include depend.phony first. The "-" tells make not to complain that it
# can't find the file.
#
-include depend.phony

// ColourCube - structure to represent a colour cube. The colour cube consists
// of its dimensions (nRed x nGreen x nBlue) and a table mapping an (r,g,b)
// triple to a pixel value.
//
// A colour cube is used in two cases. The first is internally in a viewer
// when it cannot use a trueColour format, nor can it have exclusive access to
// a writable colour map. This is most notably the case for an X viewer
// wishing to use a PseudoColor X server's default colormap.
//
// The second use is on the server side when a client has asked for a colour
// map and the server is trueColour. Instead of setting an uneven trueColour
// format like bgr233, it can set the client's colour map up with a 6x6x6
// colour cube. For this use the colour cube table has a null mapping, which
// makes it easy to perform the reverse lookup operation from pixel value to
// r,g,b values.
