-- 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().
-
-nxcompext-3.0.0-14
-
-- Removed support for Rdp, Tight and Hextile packed images encod-
-  ing since they have been made obsolete by the new NX server.
-
-- Changed the copyright attribution from Medialogic to NoMachine.
-
-nxcompext-3.0.0-13
-
-- Allocate 1024 additional bytes for the Jpeg compression, instead
-  of 512, to avoid failures on very tiny images.
-
-- 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().
-
-nxcompext-3.0.0-10
-
-- Moved the _NXRDPGlyph and _NXRDPText declarations from NXlib.h
-  to NXproto.h to force fields to be CARD32.
-
-- Fixed a typo in NXSetDisplayBuffer() that could cause a double
-  free.
-
-- Fixed a compilation error with old GCC versions.
-
-- 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.
-
