Dominik Csapak ebe1002c3d add genfont2 and unifont build-dependency 
this patch introduces a new tool to generate font data
it uses a new build-dependency, namely unifont, which is an opensource
font with printable charachters for the unicode range from
0x0000 to 0xFFFF

we generate a file which is easily mmap'able and has the same bitformat
we used before (minus the codepoint -> address translation)

note that some characters are using 2 columns as width, so to have a
static lookup, we need to make each character 32 byte long
(1 byte per line, 16 lines per terminal column)

Simple VNC terminal emulator (inspired by VncCommand)

We try to simulate a 'xterm', because we want to support:

	- unicode
	- mouse
	
and xterm seems to be the best solution for that.

some code is inspired by: qemu, VncCommand, xterm, linux kernel, ...

libvncserver
============

LibVNCServer does not suppurt TLS currently. So we staically link to a
patched versions on that library instead of using the debian shared
libraries.

VNC Java Applet (for use in web based applications):
====================================================

We use patched VncViewer files (TigerVNC 1.1.0 sources):

http://www.tigervnc.com/

We sign the applet to make clipboard working.

Note: Newer tigervnc 1.2.0 always use a toplevel window, which
make it basically useless as applet.

http://sourceforge.net/tracker/?func=detail&aid=3488166&group_id=254363&atid=1126849

I put patches for 1.2.0 to newtigerpatches subdir.

Note: javascript-events.patch requires JSObject, which is inside plugin.jar
previously provided by sun-java-jdk. For wheezy/openjdk, we need to install
package "icedtea-netx-common" which contains that file.

TODO:
=====

Useful sources for terminal emulation:
	
   xterm source: ctlseqs.txt
   http://vt100.net/docs/vt220-rm
   man 5 terminfo
   infocmp xterm
   man console_codes

Fonts: 

we currently use fonts provided by the debian console-data package:
see /usr/share/consolefonts/*

Only 8x16 fonts are supported

TODO contains a list of unimplemented things.
