See also the files in qtbase/src/3rdparty/harfbuzz, which are used by FreeType.

Parts of the FreeType projects have been modified and put into Qt for use in the painting subsystem.
These files are ftraster.h, ftraster.c, ftgrays.h and ftgrays.c. The following modifications has been made to these files:

Renamed FT_ and ft_ symbols to QT_FT_ and qt_ft_ to avoid name conflicts.
Removed parts of code not relevant when compiled with _STANDALONE_ defined.
Changed behavior in ftraster.c to follow X polygon filling rules.
Implemented support in ftraster.c for winding / odd even polygon fill rules.
Replaced bitmap generation with span generation in ftraster.c
Renamed: ftraster.h to qblackraster_p.h
Renamed: ftraster.c to qblackraster.c
Renamed: ftgrays.h to qgrayraster_p.h
Renamed: ftgrays.c to qgrayraster.c

The Catharon Open Source LICENSE
----------------------------

2000-Jul-04

Introduction
============

This license applies to source files distributed by Catharon
Productions, Inc. in several archive packages. This license
applies to all files found in such packages which do not fall
under their own explicit license.

This license was inspired by the BSD, Artistic, and IJG
(Independent JPEG Group) licenses, which all encourage inclusion
and use of free software in commercial and freeware products
alike. As a consequence, its main points are that:

o We don't promise that this software works. However, we are
interested in any kind of bug reports. (`as is' distribution)

o You can use this software for whatever you want, in parts or
full form, without having to pay us. (`royalty-free' usage)

o You may not pretend that you wrote this software. If you use
it, or only parts of it, in a program, you must acknowledge
somewhere in your documentation that you have used the
Catharon Code. (`credits')

We specifically permit and encourage the inclusion of this
software, with or without modifications, in commercial products.
We disclaim all warranties covering the packages distributed by
Catharon Productions, Inc. and assume no liability related to
their use.

Legal Terms
===========

0. Definitions
--------------

Throughout this license, the terms `Catharon Package', `package',
and `Catharon Code' refer to the set of files originally
distributed by Catharon Productions, Inc.

`You' refers to the licensee, or person using the project, where
`using' is a generic term including compiling the project's source
code as well as linking it to form a `program' or `executable'.
This program is referred to as `a program using one of the
Catharon Packages'.

This license applies to all files distributed in the original
Catharon Package(s), including all source code, binaries and
documentation, unless otherwise stated in the file in its
original, unmodified form as distributed in the original archive.
If you are unsure whether or not a particular file is covered by
this license, you must contact us to verify this.

1. No Warranty
--------------

THE CATHARON PACKAGES ARE PROVIDED `AS IS' WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OF OR THE INABILITY TO
USE THE CATHARON PACKAGE.

2. Redistribution
-----------------

This license grants a worldwide, royalty-free, perpetual and
irrevocable right and license to use, execute, perform, compile,
display, copy, create derivative works of, distribute and
sublicense the Catharon Packages (in both source and object code
forms) and derivative works thereof for any purpose; and to
authorize others to exercise some or all of the rights granted
herein, subject to the following conditions:

o Redistribution of source code must retain this license file
(`license.txt') unaltered; any additions, deletions or changes
to the original files must be clearly indicated in
accompanying documentation. The copyright notices of the
unaltered, original files must be preserved in all copies of
source files.

o Redistribution in binary form must provide a disclaimer that
states that the software is based in part on the work of
Catharon Productions, Inc. in the distribution documentation.

These conditions apply to any software derived from or based on
the Catharon Packages, not just the unmodified files. If you use
our work, you must acknowledge us. However, no fee need be paid
to us.

3. Advertising
--------------

Neither Catharon Productions, Inc. and contributors nor you shall
use the name of the other for commercial, advertising, or
promotional purposes without specific prior written permission.

We suggest, but do not require, that you use the following phrase
to refer to this software in your documentation: 'this software is
based in part on the Catharon Typography Project'.

As you have not signed this license, you are not required to
accept it. However, as the Catharon Packages are copyrighted
material, only this license, or another one contracted with the
authors, grants you the right to use, distribute, and modify it.
Therefore, by using, distributing, or modifying the Catharon
Packages, you indicate that you understand and accept all the
terms of this license.
