        Cairo is a 2D graphics library with support for multiple output
        devices.  Currently supported output targets include the X
        Window System, XCB, Quartz, Win32, image buffers, PostScript,
        PDF, and SVG file output.

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