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
