Updated for 0.0.18.

A const char * is not supposed to change and cannot be deleted. So
here is a patch that remove unnecessary const from props.hxx and
props.cxx. There also is the addition of a friend directive because
nested classes do not receive special privileges and cannot access
private members of the outer class.

+* Created a src/libs subdirectory for several packages that need to be
+  installed by the user but are used by many other packages and may already
+  be installed.  So we just bundle the source separately as a convenience
+  if the user needs to build and install these.
+* Upgrade to zlib-1.1.4 (security fix)
+* Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release)
+* Added support for point objects in the scenery file format.
+* Additions to the binary file format to make it *much* more flexible.
+  For each major primative type: points, triangles, fans, and strips, you
+  can specify an index list of vertices, normals, colors, and texture
+  coordinates.  You can skip any of these you like to save on space.
+* Added support for new file features in the binary -> ascii scenery file
+  decoder.
+* Various code clean ups.

+=============================================================================
+
+
+zlib 1.1.4 is a general purpose data compression library.  All the code
+is thread safe.  The data format used by the zlib library
+is described by RFCs (Request for Comments) 1950 to 1952 in the files 
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
+format) and rfc1952.txt (gzip format). These documents are also available in
+other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact jloup@gzip.org). A usage
+example of the library is given in the file example.c which also tests that
+the library is working correctly. Another example is given in the file
+minigzip.c. The compression library itself is composed of all source files
+except example.c and minigzip.c.
+
+To compile all files and run the test program, follow the instructions
+given at the top of Makefile. In short "make test; make install"
+should work for most machines. For Unix: "./configure; make test; make install"
+For MSDOS, use one of the special makefiles such as Makefile.msc.
+For VMS, use Make_vms.com or descrip.mms.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to
+Gilles Vollant <info@winimage.com> for the Windows DLL version.
+The zlib home page is http://www.zlib.org or http://www.gzip.org/zlib/
+Before reporting a problem, please check this site to verify that
+you have the latest version of zlib; otherwise get the latest version and
+check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html
+before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of  Dr. Dobb's Journal; a copy of the article is available in
+http://dogma.net/markn/articles/zlibtool/zlibtool.htm
+
+The changes made in version 1.1.4 are documented in the file ChangeLog.
+The only changes made since 1.1.3 are bug corrections:
+
+- ZFREE was repeated on same allocation on some error conditions.
+  This creates a security problem described in
+  http://www.zlib.org/advisory-2002-03-11.txt
+- Returned incorrect error (Z_MEM_ERROR) on some invalid data
+- Avoid accesses before window for invalid distances with inflate window
+  less than 32K.
+- force windowBits > 8 to avoid a bug in the encoder for a window size
+  of 256 bytes. (A complete fix will be available in 1.1.5).
+
+The beta version 1.1.5beta includes many more changes. A new official
+version 1.1.5 will be released as soon as extensive testing has been
+completed on it.
+
+
+Unsupported third party contributions are provided in directory "contrib".
+
+A Java implementation of zlib is available in the Java Development Kit
+http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
+See the zlib home page http://www.zlib.org for details.
+
+A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
+is in the CPAN (Comprehensive Perl Archive Network) sites
+http://www.cpan.org/modules/by-module/Compress/
+
+A Python interface to zlib written by A.M. Kuchling <amk@magnet.com>
+is available in Python 1.5 and later versions, see
+http://www.python.org/doc/lib/module-zlib.html
+
+A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com>
+is availlable at http://www.westend.com/~kupries/doc/trf/man/man.html
+
+An experimental package to read and write files in .zip format,
+written on top of zlib by Gilles Vollant <info@winimage.com>, is
+available at http://www.winimage.com/zLibDll/unzip.html
+and also in the contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
+  and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
+  The zlib DLL support was initially done by Alessandro Iacopetti and is
+  now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
+  home page at http://www.winimage.com/zLibDll
+
+  From Visual Basic, you can call the DLL functions which do not take
+  a structure as argument: compress, uncompress and all gz* functions.
+  See contrib/visual-basic.txt for more information, or get
+  http://www.tcfb.com/dowseware/cmp-z-it.zip
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization.
+  With -O, one libpng test fails. The test works in 32 bit mode (with
+  the -n32 compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1   
+  it works when compiled with cc.
+
+- on Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1
+  is necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works
+  with other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
+
+- For Turbo C the small model is supported only with reduced performance to
+  avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
+
+- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html
+  Per Harald Myrvang <perm@stud.cs.uit.no>

+Acknowledgments:
+
+  The deflate format used by zlib was defined by Phil Katz. The deflate
+  and zlib specifications were written by L. Peter Deutsch. Thanks to all the
+  people who reported problems and suggested various improvements in zlib;

+     * When calling the constructor you need to provide a host name, and a
+     * port number. The convention used by the
+     * SGSocketUDP class is that the server side listens and the client
+     * side sends. For a server socket, the host name should be
+     * empty. For a server, the port number is optional, if you do not
+     * specify a port, the system will assign one. For a client
+     * socket, you need to specify both a destination host and
+     * destination port.
+     *
+     * UDP sockets are a lower level protocol than TCP sockets and are
+     * "connectionless" in the sense that either client or server can
+     * exist, or not exist, startup, quit, etc. in any order and
+     * whenever both ends are alive, the communication succeeds. With
+     * UDP sockets, the server end just sits and listens for incoming
+     * packets from anywhere. The client end sends it's message and
+     * forgets about it. It doesn't care if there isn't even a server
+     * out there listening and all the packets are getting
+     * lost. Although systems/networks usually do a pretty good job
+     * (statistically) of getting your UDP packets to their
+     * destination, there is no guarantee that any particular packet
+     * will make it. But, because of this low level implementation and
+     * lack of error checking, UDP packets are much faster and
+     * efficient. UDP packets are good for sending positional
+     * information to synchronize two applications. In this case, you
+     * want the information to arrive as quickly as possible, and if
+     * you lose a packet, you'd rather get new updated information
+     * rather than have the system waste time resending a packet that
+     * is becoming older and older with every retry.
