    <para>
      <application>Cairo</application> is a 2D graphics library with support for
      multiple output devices. Currently supported output targets include the
      <application>X</application> Window System, win32, image buffers,
      PostScript, PDF and SVG. Experimental backends include OpenGL, Quartz and
      XCB file output. <application>Cairo</application> 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). The <application>Cairo</application> API provides operations
      similar to the drawing operators of PostScript and PDF. Operations in
      <application>Cairo</application> include stroking and filling cubic
      B&eacute;zier splines, transforming and compositing translucent images,
      and antialiased text rendering. All drawing operations can be transformed
      by any

      transformation</ulink> (scale, rotation, shear, etc.).
