+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 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.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+\f
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+\f
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, 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 library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete 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 distribute a copy of this License along with the
+Library.
+
+ 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.
+\f
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+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 Library, 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 Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+\f
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you 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.
+
+ If distribution of 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 satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+\f
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be 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.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+\f
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library 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.
+
+ 9. 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 Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+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 with
+this License.
+\f
+ 11. 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 Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library 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 Library.
+
+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.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library 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.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+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 Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+\f
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+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
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. 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 LIBRARY 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
+LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. 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 library's name and a brief idea of what it does.>

+20021208 0.7.3
+
+Fixed a typo in the python source and updated the documentation.
+
+20021207 0.7.2
+
+The perl script for the assembler include generation was replaced with a
+plain shell script in order to overcome the remote possibility of perl
+not being installed on the system TinyPTC gets built on. Now TinyPTC can
+be built as a python extension by using the excellent SWIG package, just
+use the 'python' target of the makefile and look at python_test.py.
+
+20020706 0.7.1
+
+Kevin Nickels (knickels@users.sourceforge.net) sent a patch for the BGR888
+converter that fixes the colour order on little endian platforms in the xlib
+target. A minor error in the documentation has been corrected, and the MMX
+assembly include file builder perl script has been slightly cleaned up.
+
+20020517 0.7
+
+Fred Howell wrote the XVideo target handling code and was kind enough to send
+it in order to have that included in the major next release of TinyPTC/x11. It
+has been tested both on NVidia-based cards with their binary-only drivers, on
+ATI-based cards, and with Matrox-based ones, all of them under XFree 4.x. The
+XVideo target features realtime scaling on the windowed output (fullscreen
+support will be added on a later stage...), with a lightning fast MMX converter
+from RGB to YV12. Make sure to check it out!
+
+20011103 0.6.1
+
+Version 0.6.0 was entirely done during one long coding night, so a few bugs
+were present. Anyway, I made the C functions callable by C++ as well (tested
+with g++), the example configuration file now has some enabled #defines that
+let the example work flawlessly (otherwise it won't run if you haven't got
+low-res modes defined in your X configuration. I've got them in, that's why I
+didn't notice that...). Then, g++ complained on a few targets for some
+duplicated variable definition. That's funny, gcc didn't complain. By the way,
+I also tested the whole package with GCC 3.0.1, and it works fine. So, this is
+mostly a "cleaned up" version.
+
+20011102 0.6.0
+
+After nine months, I found the time to work again on TinyPTC/X11. Big changes
+this time... First of all, now TinyPTC/X11 is released under the LGPL license,
+then I (finally) added DGA 2.0 support, although its heuristic stuff for best
+videodepth choice isn't tested at all, since my hardware supports 32bpp
+natively (if it doesn't work, please tell me, so I can attempt to fix the
+problem). Then, I splitted all the various targets in a source/header pair of
+their own, in order to improve manteniability and easy new targets addition.
+Currently you compile and link all the various targets even if you use only
+one of them but don't worry, because with some kind of #define magic and a fair
+job done by strip, the executable size won't grow at all. The makefile has been
+reworked in order to use automated dependencies and for generate automatically
+the NASM includefile for mmx.s from mmx.h. Then, I had to change a variable
+name in the supplied example due to clashes with a function with the same name.
+Oh, I also added DBE support, if you need it. Of course the documentation has
+been updated and the makefile now creates a static library called libtinyptc.a
+that can be included in your own programs without having to recompile tinyptc
+all the time. Have fun!.
+
+20010206 0.5.1
+
+The makefile now contains a different optimization flag, now the executable is
+a bit smaller (at least on my box). I updated the documentation, too (I forgot
+to add the __PTC_MEMCPY__ #define). Added a cleanup callback function, in order
+to let it be a bit more programmer-friendly. Now you can use PTC_SUCCESS and
+PTC_FAILURE in order to check the results of the TinyPTC functions you call.
+Documentation now contains NetBSD compilation workaround.
+
+20001027 0.5
+
+The mmx converters were added and the makefile was cleaned up in order to be
+a bit more flexible and to support the external assembler code. I left out a
+debug fprintf somewhere in the DGA code, now it's just history. The
+documentation was updated, too. Nothing more to say, over and out.
+
+20001306 0.4
+
+Bugs are calling... And we're supposed to fix them. There was a glitch in the
+32bpp->15bpp conversion code, thanks to tolemaC/Elerium Core for the bug
+report. Now the 24bpp conversion modules should work for big-endian machines as
+well. Try them if you've got such a system and then tell us.
+
+20000531 0.3.1
+
+Sometimes, fixing a bug, brings another one in. Well, now the only thing that
+worked was the 32bpp code. Strange, isn't it ? ;) Anyway, this is fixed now.
+
+20000527 0.3
+
+TinyPTC was developed again after a little pause. Great news this time... I
+added color conversion and it seems to work quite well, too. It's rather slow
+but I think that some compiler optimizations can speed it up a bit as well. If
+it's still too slow for you, feel free to write your own converters and submit
+them to Gaffer =) As an added bonus, the 24-32 bpp dilemma seems to be
+disappeared... Maybe it's fixed, try and see. Tell me if there's something that
+doesn't work.
+
+20000508 0.2
+
+TinyPTC was rewritten from scratch (literally), now the sources are easier to
+read and I threw some comment in, too. The XShm support is finished and seems
+to work. Tell me if I'm wrong about that. The DGA part wasn't working properly,
+it blarfed on the fullscreen-emulation blit code, now it works again. I also
+added a 'best-fit' videomode switch logic for fullscreen-emulation code.
+
+20000505 0.1.1
+
+Some kind of preliminary XShm support is now included. There wasn't an UID
+check for DGA mode (it needs Root access in order to access video memory
+directly). I forgot to include it when I joined the two x11 sourcetrees
+together (windowed and DGA). The bitdepth is incorrectly reported as 24 even on
+32bpp servers. Strangely enough, my server correctly reports 32bpp.
+The pitch value calculation method is wrong. On some cards the assumption
+pitch=width*bpp isn't true (TNT cards for example but not Banshees). Damn, I'm
+so lame... =) I was calculating it with the logical screenwidth of the
+resulting viewport instead of calculating it with the physical screenwidth
+returned in the videomode info. The makefile was modified in order to include a
+check to "tinyptc.h" during the 'make' operation.
+
+20000503 0.1
+
+Initial release. Supports X11 Windowed and X11 DGA access. No color
+conversions, just a bare bones emulation of the windows version.

+This is the only documentation you can find in this package because the
+library is pretty straightforward to use. So, here it goes:
+
+ Index:
+
+ * What is TinyPTC
+ * What TinyPTC has to offer
+ * How tiny is TinyPTC
+ * TinyPTC's usage
+ * How to compile TinyPTC
+ * DGA considerations
+ * XVideo considerations
+ * Python extension
+ * How to contact the authors
+ * Where the latest version can be found
+
+* What is TinyPTC
+
+TinyPTC is a reduced subset of OpenPTC, made exclusively with size
+optimizations in mind. TinyPTC is a somehow "low-level" graphics library
+that runs on top of XLib, providing only a few functionalities you may
+need when working with framebuffer devices.
+
+* What TinyPTC has to offer
+
+TinyPTC will simplify your programs that are using X11 to output
+graphics. It does all the grunt work for you, so your life will be easier :)
+
+Actually TinyPTC features:
+
+- Automatic display management
+ * XLib, DBE, XVideo, and Mit-Shm window management
+ * DGA 1.x support, including videomode switch and fullscreen emulation
+ * DGA 2.x support, including videomode/videodepth switch and fullscreen
+ emulation.
+
+- Automatic color conversion
+ * Detects and converts the internal 32bpp ARGB buffer to 15, 16 and
+ 24 bpp modes, both RGB and BGR. Two versions are supplied, one featuring
+ MMX conversions and one that doesn't.
+
+- Automatic event management
+ * It automatically quits when the ESC key is pressed or the window
+ is closed by the user.
+
+* How tiny is TinyPTC
+
+TinyPTC is rather small by itself, actually I can give you some
+information about the test program supplied with the library.
+
+(I'm talking about UNPACKED executables, once they've been stripped)
+
+Raw XLib 7388 bytes
+Raw XLib+Color conversion 7580 bytes (*)
+Mit-Shm 8252 bytes
+Mit-Shm+Color conversion 8421 bytes (*)
+DBE 8380 bytes
+DBE+Color conversion 8604 bytes (*)
+DGA 1.x 20860 bytes (**)
+DGA 1.x+Best Videomode 21084 bytes (**)
+DGA 1.x+Color conversion 20924 bytes (*) (**)
+DGA 1.x+Color conversion+Best Videomode 21404 bytes (*) (**)
+DGA 2.x 8028 bytes
+DGA 2.x+Best Videomode 8220 bytes
+DGA 2.x+Color conversion 8252 bytes (*)
+DGA 2.x+Color conversion+Best Videomode 9244 bytes (*)
+XVideo+Mit-Shm 22352 bytes
+XVideo+Mit-Shm+MMX conversion 19152 bytes
+
+The executables were stripped with:
+
+strip --strip-all ./executable
+strip --remove-section=".comment" ./executable
+strip --remove-section=".note" ./executable
+
+[By the way, a better "strip" does exist, it's called "sstrip". It was
+programmed by Brian Raiter, and on his site you can find further information
+about tricks you can use in order to reduce your programs' size and so on.
+Brian Raiter's page is http://www.muppetlabs.com/~breadbox/software/tiny/]
+
+(*) The color conversion modules were included all at once, you will
+ get a smaller executable if you include only the ones you need.
+
+(**) The DGA 1.x executables are so big because the library that manages
+ DGA+Videomode switch extensions is linked statically. If you look
+ at the object file you get from x11.c you'll notice the absence
+ of all those control strings like "Video memory protecting" and
+ such. I tried to link the library dynamically but the
+ executables were bigger due to the library loading code being
+ added. Hopefully with DGA 2.x those two libraries are dynamically linked.
+
+If you pack them with UPX 1.2 (or better) you'll get a 10%-50% size reduction,
+at least on my box... (I'm talking about the supplied example, of course).
+
+UPX can be found at: http://upx.sf.net
+SStrip can be found at:
+ http://www.muppetlabs.com/~breadbox/software/elfkickers.html
+
+* TinyPTC's usage
+
+TinyPTC exports just three functions you can use:
+
+ * int ptc_open(char *title, int width, int height);
+ * int ptc_update(void *buffer);
+ * void ptc_close(void);
+
+ (It can't get any simpler, can it?)
+
+ - ptc_open(char *title, int width, int height)
+
+ ptc_open() either opens the window that your application needs for blitting
+ data on the screen or it will go fullscreen. It accepts a title for the
+ window that will be created (that title will be discarded for fullscreen
+ mode) and the window size. For fullscreen mode, TinyPTC will try to find a
+ suitable videomode first, and it will emulate a fullscreen mode if it didn't
+ find any (you'll see your application's output in the middle of the screen).
+ If you enabled best-videomode-choice at compile time, the library will set
+ the best videmode that fits the supplied window size. It will return
+ PTC_FAILURE if it fails, otherwise it will return PTC_SUCCESS.
+
+ - ptc_update(void *buffer)
+
+ ptc_update() does a mere blitting of your buffer onto the screen. If
+ automatic color conversion was enabled it will do the conversion for you. It
+ will return PTC_SUCCESS if the buffer was blitted and nothing else happened,
+ else it will return PTC_FAILURE.
+
+ - ptc_close(void)
+
+ ptc_close() closes the window the library created. If it is in fullscreen
+ mode, it will switch back to normal videomode. ptc_close() is called
+ automatically when the user presses ESC or closes manually the window.
+
+Plus, there is an optional callback function that gets called when TinyPTC is
+about to shut itself down, called ptc_cleanup_callback, that you must supply if
+you are going to use that callback option. Its prototype is:
+
+ * void ptc_cleanup_callback(void);
+
+* How to compile TinyPTC
+
+First of all, Laurent Mascherpa (laurent.mascherpa@epita.fr) managed to compile
+TinyPTC with the mmx converters under NetBSD. As he told me, NetBSD uses a
+slightly different a.out object format, so the files generated by nasm are
+useless. Anyway, the workaround consists in modifying the AFLAGS variable in
+the makefile:
+
+ From:
+
+ AFLAGS = -f elf
+
+ to:
+
+ AFLAGS = -f aoutb --PREFIX _
+
+(Next time I'm going to add some sort of "autoconf"-like scripts ;))
+Please note that you'll also get a static library called libtinyptc.a, ready to
+be included in your own programs...
+
+TinyPTC's behaviour can be set with a few #define lines in the include files.
+Here's a list:
+
+ - Callback usage
+
+ __PTC_CLEANUP_CALLBACK__
+
+ Enables the use of an user-supplied callback function that is called on
+ application's exit.
+
+ - MMX usage
+
+ __PTC_MMX__
+
+ Enables the use of MMX code.
+
+ - 32 bpp blit type
+
+ __PTC_MEMCPY__
+
+ If this is defined, a single memcpy() call will be used to blit the buffer
+ (Only for 32bpp RGB modes only).
+
+ - Color conversion modules
+
+ __PTC_CONVERTER_32_TO_32_RGB888
+ __PTC_CONVERTER_32_TO_32_BGR888
+ __PTC_CONVERTER_32_TO_24_RGB888
+ __PTC_CONVERTER_32_TO_24_BGR888
+ __PTC_CONVERTER_32_TO_16_RGB565
+ __PTC_CONVERTER_32_TO_16_BGR565
+ __PTC_CONVERTER_32_TO_16_RGB555
+ __PTC_CONVERTER_32_TO_16_BGR555
+
+ __PTC_MMX_CONVERT_32_TO_32_BGR888
+ __PTC_MMX_CONVERT_32_TO_32_RGB888
+ __PTC_MMX_CONVERT_32_TO_24_BGR888
+ __PTC_MMX_CONVERT_32_TO_24_RGB888
+ __PTC_MMX_CONVERT_32_TO_16_BGR565
+ __PTC_MMX_CONVERT_32_TO_16_RGB565
+ __PTC_MMX_CONVERT_32_TO_16_BGR555
+ __PTC_MMX_CONVERT_32_TO_16_RGB555
+
+ Those #define lines, if added, enable the described color conversion module.
+ Please note that you can't just enable an MMX converter without enabling the
+ standard converter as well. It doesn't hurt performance or size because the
+ standard code isn't added if there is an MMX version avaliable.
+
+ - Output targets
+
+ The output target can be chosen by defining one of these #defines in
+ tinyptc.h:
+
+ __PTC_XLIB__ * This is the raw XLib target.
+ __PTC_XSHM__ * This is the Mit-Shm target.
+ __PTC_XDBE__ * This is the X DBE target.
+ __PTC_XDGA1__ * This is the X DGA 1.x target.
+ __PTC_XDGA2__ * This is the X DGA 2.x target.
+ __PTC_XVSHM__ * This is the XVideo+Mit-Shm target.
+
+ - Extra behaviour definitions
+
+ __PTC_ENABLE_CONVERSIONS__
+
+ If it's enabled, it activates the automatic color conversion. If you will
+ run an executable that doesn't have the conversions in on a non-32bpp
+ display, it will silently quit. Ignored for the XVideo+Mit-Shm target.
+
+ __PTC_BEST_VIDEOMODE__
+
+ Enables the best-fit videomode switching for the requested window size. This
+ works only for fullscreen executables.
+
+ - Endianness considerations
+
+ __PTC_LITTLE_ENDIAN__
+
+ Selects the right converter for 24bpp and 32bpp conversion code. Pretty
+ useless if you don't plan to support those videomodes or little endian
+ architectures. It has not been tested extensively, so don't assume it's
+ 100% working. Ignored for the XVideo+Mit-Shm target.
+
+* DGA considerations
+
+Although TinyPTC is fairly portable, the DGA mode is a XFree86-only extension
+to the X Windowing system. So if you try to compile the fullscreen support on
+a non-i386 machine it will complain. Anyway, Mit-Shm and DBE are portable as
+far as I know, so is "raw" XLib mode. Please note that you will need either be
+root in order to run fullscreen-enabled applications or set the executable as
+suid root.
+
+* XVideo considerations
+
+The XVideo support has been tested on NVidia (with binary-only drivers), ATI,
+and Matrox cards under XFree 4.x. It's totally untested on S3 Savage-based
+cards. If you happen to have such a card and want to test it out, tell us! =)
+
+* Python extension
+
+Since version 0.7.2, a python extension can be built out of TinyPTC. In order
+to get that you've got to use the python target in the makefile and copy the
+_TinyPTC.so file whereever is appropriate for your program. The python API
+replicates almost entirely the C/C++ one except for pointer management. You
+have to use the provided TinyPTC.pixel_array method to allocate the buffers
+you'll pass to TinyPTC.ptc_update. The objects returned by TinyPTC.pixel_array
+act almost like normal python arrays. In case of doubt, take a look at the
+supplied python_test.py file.
+
+Note that you need SWIG 1.3 or newer to generate the wrapper code.
