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.
