2005-10-06  Johannes E. Schindelin  <Johannes.Schindelin@gmx.de>
	* many a files: kill BackChannel and CustomClientMessage
	  support. The new extension mechanism is much more versatile.
	  To prove this, a new example shows how to implement the back
	  channel as an extension. Of course, this had to be tested, so
	  LibVNCClient now has beginnings of an extension mechanism, too.
	  And an example implementing the client side of the back channel.

2005-10-03  Johannes E. Schindelin  <Johannes.Schindelin@gmx.de>
	* libvncserver/rfbserver.c, rfb/rfb.h: add a method to the
	  extension struct which is called to enable pseudo encodings.
	  This is a versatile mechanism to enable/disable custom
	  extensions with custom clients and servers.

2005-09-28  Rohit Kumar <rokumar@novell.com>
	* examples/filetransfer.c, rfb/rfb.h, configure.ac,
	  libvncserver/{auth,cargs,main,rfbserver,sockets}.c,
	  libvncserver/tightvnc-extension/*:
	  Implement TightVNC's file transfer protocol.

2005-09-27  Rohit Kumar <rokumar@novell.com>
	* libvncserver/{cargs,sockets,main,rfbserver}.c,
	  rfb/rfb.h: Provide a generic means to extend the RFB
	  protocol: rfbRegisterProtocolExtension(extension). This
	  deprecates the current (very limited) option to override
	  rfbScreenInfoPtr->processCustomClientMessage(client).

2005-09-26  Rohit Kumar <rokumar@novell.com>
	* libvncserver/{auth,main,rfbserver}.c, rfb/{rfb,rfbproto}.h:

	  types.

	* libvncserver/{cursor.c,rfbserver.c}: fixed the "disappearing cursor"
	  problem

2005-01-18  Johannes E. Schindelin  <Johannes.Schindelin@gmx.de>
	* rfb/rfb.h libvncserver/rfbserver.c: pointerClient was still static
	* libvncserver/rfbserver.c: do not make requestedRegion empty without
	  reason.
	* almost everything: the cursor handling for clients which don't handle
	  CursorShape updates was completely broken. It originally was very
	  complicated for performance reasons, however, in most cases it made
	  performance even worse, because at idle times there was way too much
	  checking going on, and furthermore, sometimes unnecessary updates
	  were inevitable.
	  The code now is much more elegant: the ClientRec structure knows
	  exactly where it last painted the cursor, and the ScreenInfo
	  structure knows where the cursor shall be.
	  As a consequence there is no more rfbDrawCursor()/rfbUndrawCursor(),
	  no more dontSendFramebufferUpdate, and no more isCursorDrawn.
	  It is now possible to have clients which understand CursorShape
	  updates and clients which don't at the same time.
	* libvncserver/cursor.c: rfbSetCursor no longer has the option
	  freeOld; this is obsolete, as the cursor structure knows what
	  to free and what not.

2005-01-15  Karl Runge <runge@karlrunge.com>
	* rfb/rfb.h: add alphaSource and alphaPreMultiplied to rfbCursor.

	* x11vnc: -alphablend, cursors fixes, -snapfb, more tweaks and bug
	  fixes.
