- * This program is based on some ideas from the following programs:
- *
- *       the initial x11vnc.c in libvncserver (Johannes E. Schindelin)
- *	 x0rfbserver, the original native X vnc server (Jens Wagner)
- *       krfb, the KDE desktopsharing project (Tim Jansen)
- *
- * Please see http://www.karlrunge.com/x11vnc for the most up-to-date
- * information about x11vnc.  Some of the following text may be out
- * of date.
- *
- * The primary goal of this program is to create a portable and simple
- * command-line server utility that allows a VNC viewer to connect
- * to an actual X display (as the above do).  The only non-standard
- * dependency of this program is the static library libvncserver.a.
- * Although in some environments libjpeg.so or libz.so may not be
- * readily available and needs to be installed, they may be found
- * at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/,
- * respectively.  To increase portability it is written in plain C.
- *
- * Another goal is to improve performance and interactive response.
- * The algorithm of x0rfbserver was used as a base.  Many additional
- * heuristics are also applied.
- *
- * Another goal is to add many features that enable and incourage creative
- * usage and application of the tool.  Apologies for the large number
- * of options!
- *
- * To build:
- *
- * Obtain the libvncserver package (http://libvncserver.sourceforge.net).
- * As of 12/2002 this version of x11vnc.c is contained in the libvncserver
- * CVS tree and released in version 0.5.
- *
- * gcc should be used on all platforms.  To build a threaded version put
- * "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS
- * or CPPFLAGS (e.g. before running the libvncserver configure).  The
- * threaded mode is a bit more responsive, but can be unstable (e.g.
- * if more than one client the same tight or zrle encoding).
- *
- * Known shortcomings:
- *
- * The screen updates are good, but of course not perfect since the X
- * display must be continuously polled and read for changes and this is
- * slow for most hardware. This can be contrasted with receiving a change
- * callback from the X server, if that were generally possible... (UPDATE:
- * this is handled now with the X DAMAGE extension, but unfortunately
- * that doesn't seem to address the slow read from the video h/w).  So,
- * e.g., opaque moves and similar window activity can be very painful;
- * one has to modify one's behavior a bit.
- *
- * General audio at the remote display is lost unless one separately
- * sets up some audio side-channel such as esd.
- *
- * It does not appear possible to query the X server for the current
- * cursor shape.  We can use XTest to compare cursor to current window's
- * cursor, but we cannot extract what the cursor is... (UPDATE: we now
- * use XFIXES extension for this.  Also on Solaris and IRIX Overlay
- * extensions exists that allow drawing the mouse into the framebuffer)
- * 
- * The current *position* of the remote X mouse pointer is shown with
- * the -cursor option.  Further, if -cursor X is used, a trick
- * is done to at least show the root window cursor vs non-root cursor.
- * (perhaps some heuristic can be done to further distinguish cases...,
- * currently "-cursor some" is a first hack at this)
- *
- * Under XFIXES mode for showing the cursor shape, the cursor may be
- * poorly approximated if it has transparency (alpha channel).
- *
- * Windows using visuals other than the default X visual may have
- * their colors messed up.  When using 8bpp indexed color, the colormap
- * is attempted to be followed, but may become out of date.  Use the
- * -flashcmap option to have colormap flashing as the pointer moves
- * windows with private colormaps (slow).  Displays with mixed depth 8 and
- * 24 visuals will incorrectly display windows using the non-default one.
- * On Sun and Sgi hardware we can to work around this with -overlay.
- *
- * Feature -id <windowid> can be picky: it can crash for things like
- * the window not sufficiently mapped into server memory, etc (UPDATE:
- * we now use the -xrandr mechanisms to trap errors more robustly for
- * this mode).  SaveUnders menus, popups, etc will not be seen.
- *
- * Under some situations the keysym unmapping is not correct, especially
- * if the two keyboards correspond to different languages.  The -modtweak
- * option is the default and corrects most problems. One can use the
- * -xkb option to try to use the XKEYBOARD extension to clear up any
- * remaining problems.
- *
- * Occasionally, a few tile updates can be missed leaving a patch of
- * color that needs to be refreshed.  This may only be when threaded,
- * which is no longer the default.
- *
- * There seems to be a serious bug with simultaneous clients when
- * threaded, currently the only workaround in this case is -nothreads
- * (which is now the default).
