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.
