    "Cairo is a 2D graphics library with support for multiple output devices.
Currently supported output targets include the X Window System (via both
Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file
output.  Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

Cairo is designed to produce consistent output on all output media while
taking advantage of display hardware acceleration when available
eg. through the X Render Extension).

The cairo API provides operations similar to the drawing operators of
PostScript and PDF.  Operations in cairo including stroking and filling cubic
Bézier splines, transforming and compositing translucent images, and
antialiased text rendering.  All drawing operations can be transformed by any
affine transformation (scale, rotation, shear, etc.).")

    (description "Pango is a library for laying out and rendering text, with an
emphasis on internationalization.  Pango can be used anywhere that text layout
is needed, but using Pango in conjunction with Cairo and/or Gtk2 provides a
complete solution with high quality text handling and graphics rendering.

Dynamically loaded modules handle text layout for particular combinations of
script and font backend.  Pango provides a wide selection of modules, including
modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts.
Virtually all of the world's major scripts are supported.

In addition to the low level layout rendering routines, Pango includes
@code{Pango::Layout}, a high level driver for laying out entire blocks of text,
and routines to assist in editing internationalized text.")
