+nxcompext-3.3.0-1
+
+- Opened the 3.3.0 branch based on nxcompext-3.2.0-1.
+
+nxcompext-3.2.0-1
+
+- Opened the 3.2.0 branch based on nxcompext-3.1.0-2.
+
+nxcompext-3.1.0-2
+
+- Updated file VERSION to match the current release version.

+- Removed the remaining debug output.
+
+nxcompext-3.0.0-17
+
+- Changed the copyright notices at the beginning of the files that
+ were referring to NXPROXY to refer to NXCOMPEXT.
+
+nxcompext-3.0.0-16
+
+- Handle the reply failure in NXGetShmemParameters().
+
+nxcompext-3.0.0-15
+
+- Separated the functionalities made available by NXQueryDisplay()
+ in three distinct functions:
+
+ NXDisplayReadable() Query the number of bytes readable from
+ the display connection.
+
+ NXDisplayFlushable() Query the number of the outstanding bytes
+ to flush to the display connection.
+
+ NXDisplayCongestion() Return a value between 0 and 9 indicating
+ the congestion level of the NX transport.
+
+- Renamed NXQueryDisplayError() to NXDisplayError().

+
+- Removed support for the special *PNG_JPEG* pack method.
+
+nxcompext-3.0.0-12
+
+- Implemented the NXEncodeBitmap() method. This is a very simple
+ encoder removing the 4th byte in 32 bits-per-plane images. For
+ the other pixmap depths it simply returns a pointer to the orig-
+ inal image data, saving the copy. This encoding is intended to
+ better leverage the stream compression on low bandwidth links.
+
+- Removed the quality parameter from the RGB/RLE encoding function.
+
+nxcompext-3.0.0-11
+
+- Removed the additional parameter in the call to NXTransFlush().

+
+- Removed the warning issued on AMD64 when compiling with the logs
+ enabled.
+
+nxcompext-3.0.0-9
+
+- Added the NXDisplayCongestion query type to NXQueryDisplay(). It
+ returns a value between 0 and 9, with 9 meaning that the link is
+ congested and no further data can be sent.
+
+- Added the NXSetDisplayBuffer() function. It allows the caller to
+ set the display output buffer size at runtime.
+
+- Removed the congestion and synchronization callbacks.
+
+nxcompext-3.0.0-8
+
+- Removed the warnings issued when purging the collected data at
+ display reset.
+
+nxcompext-3.0.0-7
+
+- Added the NXSetDisplayWriteHandler() interface. The function
+ registers a callback that will be invoked every time more data
+ is written to the display socket.
+
+nxcompext-3.0.0-6
+
+- Made NXQueryDisplay() take into account the bytes in the display
+ buffer when queried for the bytes flushable.
+
+nxcompext-3.0.0-5
+
+- Added file COPYING.
+
+nxcompext-3.0.0-4
+
+- Updated copyright notices to the current year.
+
+nxcompext-3.0.0-3
+
+- Imported changes up to nxcompext-2.1.0-4.
+
+- Fixed TR12D01564. Changed configure script to build library with
+ -fPIC option.
+
+- Added 256 byte to the size of Jpeg destination buffer.
+
+nxcompext-3.0.0-2
+
+- Updated the file VERSION.
+
+nxcompext-3.0.0-1
+
+- Opened the 3.0.0 branch based on nxcompext-2.0.0-33.
+
+nxcompext-2.0.0-33
+
+- Placed the inclusion of jpeglib.h after the X includes to fix a
+ possible compilation error.
+
+nxcompext-2.0.0-32
+
+- Avoid to copy the data to the scratch buffer and yield the task
+ of padding the output to _XSend() in the NXPutPackedImage(), NX-
+ SetUnpackAlpha() and NXSetUnpackColormap() requests.
+
+- Added support for the RLE pack method.
+
+nxcompext-2.0.0-31
+
+- The X_NXSetUnpackColormap and X_NXSetUnpackAlpha now carry their
+ data in compressed form. The alpha data is compressed using the
+ ZLIB RLE encoding, while the colormap data is compressed using
+ the default ZLIB deflate.
+
+- Created new message structures to handle the compatibility with
+ the old proxy versions. When connected to an old proxy version
+ the agent should use the NXSetUnpackColormapCompat() and NXSet-
+ UnpackAlpha() interfaces.
+
+nxcompext-2.0.0-30
+
+- Removed the unfriendly warning printed if a client tried to reset
+ the library multiple times.
+
+nxcompext-2.0.0-29
+
+- Made possible to compile even if makedepend is not found.
+
+nxcompext-2.0.0-28
+
+- Added the NXSetDisplaySynchronizationHandler() interface. The NX
+ transport will use the callback to report when the agent can use
+ the available bandwidth to synchronize the X objects that are
+ corrupted or incomplete.
+
+- Bytes from 14 to 24 in the NXGetControlParameters() reply report,
+ respectively, the frame timeout, the ping timeout, the preferred
+ image split mode and the split size threshold.
+
+nxcompext-2.0.0-27
+
+- Changed the image cleanup functions and the Png and Jpeg encoders
+ to be independent from the host endianess.
+
+- Enabled again the image cleanup on big endian machines.
+
+nxcompext-2.0.0-26
+
+- Added the NXAbortSplit() request.
+
+- Added information about the size of the shared memory segment used
+ by the remote proxy in the NXGetShmemParameters() reply.
+
+nxcompext-2.0.0-25
+
+- Renamed the NXGetSplitResource() and NXGetUnpackResource() utili-
+ ties to NXAllocSplit() and NXAllocUnpack(). They can be called
+ with a NXAnyResource parameter to get the first available id or
+ requre a specific resource. From this version the resource must
+ be explicitly reserved. NXFreeUnpack() and NXFreeSplit() check
+ if the resource was allocated and don't do anything if it is not
+ the case. NXAllocSplit() and NXAllocUnpack() return NXNoResource
+ if the resource can't be reserved.
+
+nxcompext-2.0.0-24
+
+- NXFlushDisplay() now verifies whether the XlibDisplayWriting flag
+ is set before flushing the display buffer. in this case, it only
+ flushes the NX link.
+
+nxcompext-2.0.0-23
+
+- Implemented a move-to-front strategy for the image cache, to mi-
+ nimize the number of lookups.
+
+- Fixed the problems imtroduced by the new cache implementation by
+ modifying the memory allocation routines in Jpeg.c and Pgn.c.
+
+- Temporarily fixed the cleanup problems on big-endian machines by
+ skipping the operation.
+
+- Added a NXSetDisplayStatisticsHandler() to let the agent include
+ arbitrary data in the transport statistics. The parameter is a
+ pointer to a pointer to a null terminated string. The pointer is
+ set at the time the handler is registered. The pointed string can
+ be filled by the agent with its statistics data.
+
+nxcompext-2.0.0-22
+
+- The NXCacheFindImage() returns a pointer to the checksum, if the
+ image is found.
+
+- The image cache uses the data passed to NXCacheAddImage() instead
+ of making a copy.
+
+- The Z stream used by the RGB encoder is allocated at initializat-
+ ion and freed at reset.
+
+nxcompext-2.0.0-21
+
+- Removed the reliance on the local byte order in the image cleanup
+ functions.
+
+nxcompext-2.0.0-20
+
+- Added the NXFinishSplit() request. It forces the proxy to comple-
+ tely transfer all the split messages for the given resource, and
+ then notify the agent.
+
+nxcompext-2.0.0-19
+
+- Enabled again the cleanup of images.
+
+- Updated to comply with the new NXTransFlush() interface.
+
+nxcompext-2.0.0-18
+
+- Moved all the declarations in Rgb.c at the beginning of the block
+ to avoid the possible compilation errors with old compilers.
+
+nxcompext-2.0.0-17
+
+- Added a new RGB image encoder. For now the encoder uses a static
+ Z stream to compress the image data in the destination buffer and
+ allows the agent to use the simplest encoding by still separating
+ the alpha channel from the image data. The new encoder can be the
+ the base for implementing color reduction by dithering or a color-
+ mapped translation of the image similar to PNG, but without the
+ PNG overhead and with the colormap being sent to the client using
+ the NXSetUnpackColormap() opcode.
+
+- Created a new NXCleanImage() function that takes a XImage pointer
+ and uses either the CleanXYImage() or the CleanZImage() routines
+ to cleanup the padding bits.
+
+nxcompext-2.0.0-16
+
+- Added a parameter to NXFlushDisplay() to specify what needs to be
+ flushed. The parameter can be one the following values, defined
+ in NXvars.h:
+
+ NXFlushBuffer Only the Xlib buffer is to be flushed.
+
+ NXFlushLink Flush both the Xlib buffer and any pending
+ data encoded by the NX transport.
+
+ NXFlushIdle Inform the NX transport that the agent is
+ idle. This will let the NX transport encode
+ more low-priority data, and then flush the
+ link.
+
+- Ensured that the padding bytes are cleaned when creating a new
+ PNG image. It seems that some images are still missed. This is
+ to be investigated.
+
+nxcompext-2.0.0-15
+
+- Ensured that the packed image cache is recreated only on a size
+ change.
+
+nxcompext-2.0.0-14
+
+- Updated to get the karma delay field from the X_NXGetControlPara-
+ meters reply.
+
+nxcompext-2.0.0-13
+
+- Added the NXSetDisplayPolicy() and NXSetDisplayFlushHandler() in-
+ terfaces. The second function registers a callback that will be
+ invoked by the NX transport when the number of bytes encoded by
+ the proxy exceeds the threshold set for the scheduled write.
+
+- Added the NXFlushDisplay() and NXQueryDisplay() interfaces. They
+ are used to hide the corresponding NX transport functions to the
+ application. NXQueryDisplay() can be called with the NXDisplay-
+ Flushable or NXDisplayReadable parameters, to get, repectively,
+ the number of bytes that are queued to the NX transport and the
+ number of bytes that is possible to read.
+
+- Included the remote proxy version in the NXGetControlParameter()
+ reply.
+
+nxcompext-2.0.0-12
+
+- Added the NXGetSplitResource() and NXGetUnpackResource utilities.
+ These can be used by the client to find out the first unused id
+ available for a split or unpack operation.
+
+- Added the NXFreeSplit() request function. It makes the resource
+ available for the next operation and tells the proxy to destroy
+ all the storage associated to the split.
+
+- Renamed the NXNumberOfConnections constant to NXNumberOfResources.
+
+nxcompext-2.0.0-11
+
+- Changed NXForceDisplayError() to also shut down the NX transport
+ by calling NXTransClose().
+
+- Updated to comply with the new NX function prototypes introduced
+ in nxcomp-2.0.0-31.
+
+nxcompext-2.0.0-10
+
+- NXQueryDisplayError() now checks the predicate function only if
+ the I/O error was not encountered already.
+
+nxcompext-2.0.0-9
+
+- Added the NXSetDisplayErrorPredicate(), NXSetDisplayBlockHand-
+ ler(), NXSetDisplayCongestionHandler(), NXSetLostSequenceHand-
+ ler() interfaces to let the user set the values used internal-
+ ly. All functions return the previous handler. See ChangeLog
+ in nx-X11-2.0.0-16 and nx-X11-2.0.0-17.
+
+- Moved all the internal variables shared between Xlib, nxcompext
+ and the X server in nxcomp. Declarations and function prototypes
+ moved to NXvars.h.
+
+- Some name changes. In particular the NXContinueOnDisplayError()
+ function iss renamed NXHandleDisplayError() and NXDisplayError()
+ is now renamed NXQueryDisplayError(). To verify if the display
+ is valid, NXQueryDisplayError() will now call the _NXDisplayEr-
+ rorPredicate function, or, if the predicate function is not set,
+ will simply check the value of the XlibDisplayIOError flag.
+
+- Removed the NXGetCleanupParameters() and NXGetImageParameters()
+ interfaces and the remaining references to the unused display
+ buffer and image cleanup functions.
+
+- Updated the NoMachine copyright notice to year 2006.
+
+nxcompext-2.0.0-8
+
+- Removed the unused screen parameter from XSetUnpackGeometry().
+
+- NXSetUnpackGeometry() now fails if no visual is provided.
+
+nxcompext-2.0.0-7
+
+- Changed the LICENSE file to state that the software is only made
+ available under the version 2 of the GPL.
+
+- Removed the misplaced DXPC copyright notices from the license.
+ They were copied from NXCOMP but they don't apply in any way to
+ NXCOMPEXT.
+
+nxcompext-2.0.0-6
+
+- Added the NXSetCacheParameters() request. It tells to the local
+ proxy how to handle the X requests, namely if the next requests
+ have to be stored in the memory cache, split in smal data chunks,
+ and in the case of images, saved on disk in the persistent image
+ cache. The request will affect all X messages, including plain
+ and packed images. It can be used to tell the proxy to discard
+ images coming from some selected operations, like GLX or XVideo.
+
+nxcompext-2.0.0-5
+
+- Added the NXGetFontParameters() request and reply. If the proxy
+ has been configured accordingly, the request returns the X font
+ path that can be set by the agent to tunnel the font server con-
+ nections through the NX link.
+
+nxcompext-2.0.0-4
+
+- Initial work on font server tunneling.
+
+nxcompext-2.0.0-3
+
+- Renamed the NXSetExposeEvents request to NXSetExposeParameters.
+
+nxcompext-2.0.0-2
+
+- Modified the configure and the makefiles to support the Cygwin
+ environment.
+
+- Renamed Png.h to Pgn.h to avoid name clashes on Windows.
+
+- The distclean target now removes the autom4te.cache directory.
+
+nxcompext-2.0.0-1
+
+- Opened the 2.0.0 branch based on nxcompext-1.5.0-20.
+
+nxcompext-1.5.0-20
+
+- Removed the code installing a SIGSEGV handler before trying to
+ clean an image in NXCleanImageInPlace().
+
+nxcompext-1.5.0-19
+
+- Added the NXUnsetLibraryPath() function to specify the behaviour
+ of the Popen() in the X server. If the _NXUnsetLibraryPath flag
+ is set, the Popen() will remove the LD_LIBRARY_PATH variable from
+ the environment before running the child process. This will cause
+ the X server to run the process (for example the keyboard initia-
+ lization utilities) by using the native system libraries, instead
+ of the libraries shipped with the NX environment.
+
+nxcompext-1.5.0-18
+
+- Moved the declarations of _NXEnable* and related structures from
+ Xlibint.h to NXlibint.h.
+
+- Use the include files from nx-X11 if the nx-X11/include directory
+ is found. The previous configure checked the presence of nx-X11/
+ exports/include, that might not be built at the time this library
+ is compiled.
+
+nxcompext-1.5.0-17
+
+- Added the -fPIC GCC flag when compiling on AMD64 architectures.
+
+- Removed all warnings when compiling with GCC4.
+
+- Small changes to configure.in to have specific CFLAGS.
+
+- Created a new configure using autoconf 2.59.
+
+nxcompext-1.5.0-16
+
+- Added the 'mode' field in the NXStartSplit() request. It determi-
+ nes the strategy that the proxy will adopt to handle the image.
+ If set to 'eager', the proxy will only split the messages whose
+ size exceeds the split threshold (the threshold can be found in
+ the NXGetControlParameters() reply). If mode is set to lazy, the
+ proxy will split any image that it is not able to find in its
+ cache.
+
+ The opcode and the two available modes are defined in NXproto.h,
+ currently:
+
+ #define NXSplitModeDefault 0
+ #define NXSplitModeEager 1
+ #define NXSplitModeLazy 2
+
+- All requests related to image streaming now carry a 'resource' id.
+ The id is currently ignored by the proxy in the case of NXCommit-
+ Split() requests.
+
+nxcompext-1.5.0-15
+
+- Removed the NXSync() and NXKarma() operations, not used anymore
+ by the NX agents.
+
+- Updated to comply with changes occurred in the numbering of the
+ notification events and in the interface to the image streaming
+ functions.
+
+nxcompext-1.5.0-14
+
+- Accounted for the missing xoffset field in clean-up of XYPixmaps.
+
+nxcompext-1.5.0-13
+
+- Added a 'commit' field in NXCommitSplit(). When zero, the remote
+ proxy will remove the message from the split store, without send-
+ ing the recomposed image to the X server.
+
+nxcompext-1.5.0-12
+
+- Added the NXContinueOnDisplayError() function to specify the be-
+ haviour of the Xlib I/O error handler. If the flag is set to true,
+ Xlib will simply return, instead of quitting the program. This
+ leaves to the application the responsibility of checking the sta-
+ te of the XlibDisplayIOError flag.
+
+- Changed NXDisplayIsValid() to NXDisplayError() and inverted the
+ logic. Now the function returns true if the display pointer is
+ NULL or the XlibDisplayIOError flag is set.
+
+- Added the NXForceDisplayError() function, to shutdown the display
+ descriptor and force Xlib to set the I/O error flag.
+
+nxcompext-1.5.0-11
+
+- Added -I../nx-X11/exports/include to CCINCLUDES in Makefile.in.
+
+nxcompext-1.5.0-10
+
+- Added FindLSB() to replace ffs() that may be not present on some
+ systems.
+
+- Some cosmetic changes.
+
+nxcompext-1.5.0-9
+
+- Fixed a printf() that prevented the code to compile if TEST was
+ enabled.
+
+nxcompext-1.5.0-8
+
+- Implemented the NXLib interface for asynchronous handling of the
+ XGetInputFocus requests and replies.
+
+nxcompext-1.5.0-7
+
+- Removed the _NXFlushSize parameter. New agents run the NX trans-
+ port in-process, so we don't get any benefit from increasing the
+ display buffer size.
+
+nxcompext-1.5.0-6
+
+- Added a NXDisplayIsValid() to check that the display is not NULL
+ and that the descriptor was not shut down after an IOError. The
+ reason a function is needed for this is that the flags field is
+ only in Xlibint and it is not visible to Xlib applications.
+
+nxcompext-1.5.0-5
+
+- Added the NXGetCollect*Resource utility functions, returning the
+ first available small integer resource id that can be used in a
+ subsequent collect request.
+
+nxcompext-1.5.0-4
+
+- Added the NXNumberOfConnections constant.
+
+nxcompext-1.5.0-3
+
+- Implemented the NXLib interface for the asynchronous handling of
+ the XGrabPointer requests and replies.
+
+- Solved an error in image cleaning that prevented the 8 bits-per-
+ pixel images to be completely cleaned. Due to the bug, only half
+ of the total lines were cleaned.
+
+- Removed a bug that prevented the cleaning of XYPixmaps images of
+ bitmap unit 32 and byte order LSB.
+
+- Renamed the NXImageCache variables to show they are global. They
+ are currently used in the nxagent code.
+
+nxcompext-1.5.0-2
+
+- Changed VERSION file.
+
+nxcompext-1.5.0-1
+
+- Opened the 1.5.0 branch.
+
+nxcompext-1.4.1-1
+
+- Removed the configure option --with-static. There are two options
+ now, --with-static-png and --with-static-jpeg, to offer a greater
+ degree of control on the resulting library.
+
+- This version differs from the 1.4.0-3-KRY1 in the way that the con-
+ figure script is generated by GNU Autoconf 2.57, the same version
+ used for nxcomp.
+
+- Opened the 1.4.1 branch.
+
+nxcompext-1.4.0-3
+
+- Updated the VERSION file to reflect the 1.4.0 status.
+
+nxcompext-1.4.0-2
+
+- Imported changes from the latest 1.3.2 development branch.
+
+- The 1.4.0 branch already had a 1.4.0-1 version. The changes from
+ the 1.4.0-1 were up to date with the 1.3.2-2 version.
+
+nxcompext-1.3.2-6
+
+- Fixed problem with icons in KDE and Mozilla on SPARC Solaris. The
+ problem was related to cleaning of one-bit XYPixmaps on big-endian
+ hosts, where shift of the cleaning mask executed in the wrong di-
+ rection.
+
+nxcompext-1.3.2-5
+
+- Changes in Clean.c to compile on Solaris.
+
+nxcompext-1.3.2-4
+
+- Fixed a bug in clean image procedures for 1bit XYPixmaps. The bug
+ caused Mozilla to trash some transparent icons in web pages and
+ the toolbar.
+
+- Added cleaning of the padding bytes at the end of the data chunk
+ inside XImage structure
+
+- Implemented handling of SIGSEGV during cleanup in case of static
+ data.
+
+- Moved image cleanup and masking code in new Clean.c and Mask.c
+ sources.
+
+- Corrected few typos in NXCollectImage code.
+
+nxcompext-1.3.2-2
+
+- Imported 1.4.0-1 changes from the 1.4.0 development branch.
+
+- Modified NXAllocColors to handle errors generated allocating
+ each requested color. A per-color result code is now returned
+ to the caller.
+
+- Code cleanup in Png.h and Png.c.
+
+nxcompext-1.3.2-1
+
+- Opened the 1.3.2 branch.
+
+nxcompext-1.3.1-2
+
+- Removed the underline characters and added a colon in the
+ title of this ChangeLog to fully comply with format used in
+ the release notices.
+
+nxcompext-1.3.1-1
+
+- Opened the 1.3.1 branch.
+
+nxcompext-1.3.0-18
+
+- Added the _NXLostSequenceHandler function to let NX agents
+ suppress the error message and modify the default Xlib
+ behaviour when out-of-order sequence numbers are received.
+ Pointer to function is assigned to _NXLostSequenceFunction
+ in XlibInt.c.
+
+- Original output buffer size in stock XFree86 is 2048. We try
+ to reduce context switches and help stream compression by
+ increasing the maximum size of the buffer 8192. _NXFlushSize
+ determines when the display buffer is actually flushed. It is
+ set by default to 4096 in XlibInt.c and set to 0 to use the
+ maximum available size at the time NXGetControlParameters()
+ is called.
+
+nxcompext-1.3.0-17
+
+- In handling of asynchronous GetProperty replies a warning
+ message was printed in session log when a null property was
+ stored in the state structure. This message is now printed
+ only if TEST is defined.
+
+nxcompext-1.3.0-16
+
+- Added asynchronous handling of GetProperty request and reply
+ by means of the NXCollectProperty and NXGetCollectedProperty
+ requests and the NXCollectPropertyNotify event.
+
+nxcompext-1.3.0-15
+
+- Added 4 new fields to the X_NXGetControlParameters reply.
+
+nxcompext-1.3.0-14
+
+- Added request X_NXFreeUnpack to free the resources allocated
+ by the remote proxy to unpack images for the given agent's
+ client
+
+nxcompext-1.3.0-13
+
+- Modified the following requests to carry the id of the
+ agent's client in the field resource:
+
+ - X_NXSetUnpackGeometry
+ - X_NXSetUnpackColormap
+ - X_NXSetUnpackAlpha
+ - X_NXPutPackedImage
+
+nxcompext-1.3.0-11
+
+- Modified the MIT-SHM initialization procedure to always send
+ all the 3 protocol requests also in the case of early failures.
+
+nxcompext-1.3.0-10
+
+- Added handling of X_NXSetUnpackAlpha request.
+
+- It has been made possible to send both X_NXSetUnpackColormap
+ and X_NXSetUnpackAlpha messages with 0 entries to temporarily
+ disable use of the colormap or the alpha channel and free the
+ resources allocated by the remote proxy.
+
+nxcompext-1.3.0-9
+
+- Solved a compatibility problem when mixing proxy versions
+ 1.2.2 and 1.3.0 due to the missing X_NXGetShmemParameters
+ request.
+
+nxcompext-1.3.0-7
+
+- Reduced the number of requests needed to setup the shared
+ segment at X server proxy from 4 to 3.
+
+- Small changes to the shared memory interface to support
+ path X agent to X client proxy.
+
+nxcompext-1.3.0-6
+
+- Implemented initial support for MIT-SHM extension in the
+ network path between the X server proxy and the real X
+ server.
+
+- Configure script now checks for the FreeBSD environment.
+
+- New configure script generated using autoconf-2.57-3.
+
+- Removed the XFree86 CCDEFINES from Makefile.in.
+
+nxcompext-1.3.0-5
+
+- Cosmetic changes.
+
+- Started to convert configure.in to the new layout adopted
+ for nxcomp.
+
+- Created file CHANGELOG.
+
+nxcompext-1.3.0-4
+
+- More fixes in image clean-up.
+
+nxcompext-1.3.0-3
+
+- Many fixes in image clean-up functions to handle differences
+ in endianess between client and X server.
+
+nxcompext-1.3.0-2
+
+- Modified configure.in to compile under Solaris.
+
+nxcompext-1.3.0-1

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser 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
+
+ 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) <year> <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.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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.

+
+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

+ * requests, like a SetUnpackColormap() and SetUnpackAlpha()
+ * that will be later used to decompress the image to its ori-
+ * ginal form. Multiple requests may be also generated because
+ * of the maximum size of a X request being exceeded, so that
+ * Xlib has to divide the single image in multiple sub-image re-
+ * quests. The agent doesn't need to take care of these details
+ * but will rather have to track the result of the split opera-
+ * tion. By monitoring the notify events sent by the proxy, the
+ * agent will have to implement its own strategy to deal with
+ * the resources. For example, it will be able to:
+ *
+ * - Mark a drawable as dirty, if the image was not sent
+ * synchronously, in the main X oputput stream.
+ *
+ * - Choose to commit or discard the original image, at the
+ * time it will be recomposed at the remote side. This may
+ * include all the messages that were part of the split
+ * (the colormap, the alpha channel, etc.)
+ *
+ * - Mark the drawable as clean again, if the image was
+ * committed and the drawable didn't change in the mean-
+ * while.
+ *
+ * At the time the proxy receives the end-split, it reports the
+ * result of the operation to the agent. The agent will be able
+ * to identify the original split operation (the one referenced
+ * in the start-split/end-split sequence) by the small integer
+ * number (0-255) named 'resource' sent in the events.
+ *
+ * One of the following cases may be encountered:
+ *
+ *
+ * NXNoSplitNotify All messages were sent in the main out-
+ * put stream, so that no split actually
+ * took place.
+ *
+ * NXStartSplitNotify One or more messages were split, so,
+ * at discrection of the agent, the client
+ * may be suspended until the transferral
+ * is completed.
+ *
+ * NXCommitSplitNotify One of the requests that made up the
+ * split was recomposed. The agent should
+ * either commit the given request or tell
+ * the proxy to discard it.
+ *
+ * NXEndSplitNotify The split was duly completed. The agent
+ * can restart the client.
+ *
+ * NXEmptySplitNotify No more split operation are pending.
+ * The agent can use this information to
+ * implement specific strategies requiring
+ * that all messages have been recomposed
+ * at the remote end, like updating the
+ * drawables that were not synchronized
+ * because of the lazy encoding.
+ *
+ * The 'mode' field that is sent by the agent in the start-split
+ * request, determines the strategy that the proxy will adopt to
+ * deal with the image. If set to 'eager', the proxy will only
+ * split the messages whose size exceeds the split threshold (the
+ * current threshold can be found in the NXGetControlParameters()
+ * reply). If the mode is set to lazy, the proxy will split any
+ * image that would have generated an actual transfer of the data
+ * part (in practice all images that are not found in the cache).
+ * This second strategy can be leveraged by an agent to further
+ * reduce the bandwidth requirements. For example, by setting the
+ * mode to lazy and by monitoring the result, an agent can easi-
+ * ly verify if the drawable was successfully updated, mark the
+ * drawable if not, and synchronize it at later time.
+ *
+ * See NXproto.h for the definition of the available modes.

+1. To compile:
+
+ > tar zxvf nxcompext-X.Y.Z-N.tar.gz
+ > cd nxcompext
+ > ./configure
+ > make
+
+ You'll have to run gmake under Solaris.
+
+2. The 'make install' target is not currently supported
+ in the Makefile, but it should be simple to fix.
