Notable improvements in Pango since version 1.6 include:
* New script support: Lao, Sinhala, Syriac, Tibetan
* PangoRenderer, a base object holding the logic for rendering PangoLayout
which was previously duplicated in many places.
* Transformed rendering support for the Xft backend
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

This is a stable release providing new functionality as compared
to Pango-1.2, while maintaining source and binary compatibility.
Notable improvements in Pango since version 1.2:
* Support for characters beyond the basic-multilingual
plane of Unicode and updates of character properties to
match Unicode-4.0.
* The same modules are now used for the Xft and fontconfig
backends, reducing code duplication, and making it easier
to create new backends independent of Pango that use
fontconfig and FreeType.
* A better font and shaper selection algorithm is now used
that takes script information into account.
* Bidirectional base direction can now be automatically
determined from the text instead of explicitly set by
the application.
* Improvements to OpenType handling, especially for the GPOS
table. GPOS features are now enabled for Arabic.
installs are something like databases that need to be handled automatically
by the package system during installation of modules, not by the end user.
Bump PKGREVISION to 1. (As a side effect, the package gets simplified a lot).
There are no packages in pkgsrc installing pango modules at the moment.
When they come, we can easily add a framework to handle them, as has been
done for x11/gtk2.

Pango is a library for layout and rendering of text, with an emphasis
on internationalization. Pango can be used anywhere that text layout
is needed; however, most of the work on Pango-1.0 was done using the
GTK+ widget toolkit as a test platform. Pango forms the core of text
and font handling for GTK+-2.0.
Pango is designed to be modular; the core Pango layout can be used
with four different font backends:
- Core X windowing system fonts
- Client-side fonts on X using the Xft library
- Direct rendering of scalable fonts using the FreeType library
- Native fonts on Microsoft backends
Dynamically loaded modules then handle text layout for particular
combinations of script and font backend.
As well as the low level layout rendering routines, Pango includes
PangoLayout, a high level driver for laying out entire blocks of text,
and routines to assist in editing internationalized text.
