* <Title>
* Cache Sub-System
*
* <Abstract>
* How to cache face, size, and glyph data with FreeType 2.
*
* <Description>
* This section describes the FreeType 2 cache sub-system, which is used
* to limit the number of concurrently opened @FT_Face and @FT_Size
* objects, as well as caching information like character maps and glyph
* images while limiting their maximum memory usage.
*
* Note that all types and functions begin with the `FTC_' prefix.
*
* The cache is highly portable and thus doesn't know anything about the
* fonts installed on your system, or how to access them. This implies
* the following scheme:
*
* First, available or installed font faces are uniquely identified by
* @FTC_FaceID values, provided to the cache by the client. Note that
* the cache only stores and compares these values, and doesn't try to
* interpret them in any way.
*
* Second, the cache calls, only when needed, a client-provided function
* to convert a @FTC_FaceID into a new @FT_Face object. The latter is
* then completely managed by the cache, including its termination
* through @FT_Done_Face.
*
* Clients are free to map face IDs to anything else. The most simple
* usage is to associate them to a (pathname,face_index) pair that is
* used to call @FT_New_Face. However, more complex schemes are also
* possible.
*
* Note that for the cache to work correctly, the face ID values must be
* *persistent*, which means that the contents they point to should not
* change at runtime, or that their value should not become invalid.
*
* If this is unavoidable (e.g., when a font is uninstalled at runtime),
* you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
* the cache get rid of any references to the old @FTC_FaceID it may
* keep internally. Failure to do so will lead to incorrect behaviour
* or even crashes.
*
* To use the cache, start with calling @FTC_Manager_New to create a new
* @FTC_Manager object, which models a single cache instance. You can
* then look up @FT_Face and @FT_Size objects with
* @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
*
* If you want to use the charmap caching, call @FTC_CMapCache_New, then
* later use @FTC_CMapCache_Lookup to perform the equivalent of
* @FT_Get_Char_Index, only much faster.
*
* If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
* later use @FTC_ImageCache_Lookup to retrieve the corresponding
* @FT_Glyph objects from the cache.
*
* If you need lots of small bitmaps, it is much more memory efficient
* to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
* returns @FTC_SBitRec structures, which are used to store small
* bitmaps directly. (A small bitmap is one whose metrics and
* dimensions all fit into 8-bit integers).
*
* We hope to also provide a kerning cache in the near future.

The Catharon Open Source LICENSE
----------------------------
2000-Jul-04
Copyright (C) 2000 by Catharon Productions, Inc.
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.
The Catharon Packages are copyright (C) 2000 by Catharon
Productions, Inc. All rights reserved except as specified below.
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.
