   (synopsis "2D graphics library")
   (description
    "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.)")
