+create high-quality vector (PDF, PostScript and SVG) and bitmap
+output (PNG,JPEG,TIFF), and high-quality rendering in displays (X11
+and Win32).  Since it uses the same back-end for all output, copying
+across formats is WYSIWYG.  Files are created without the dependence
+on X11 or other external programs.  This device supports alpha
+channel (semi-transparent drawing) and resulting images can contain
+transparent and semi-transparent regions.  It is ideal for use in
+server environments (file output) and as a replacement for other
+devices that don't have Cairo's capabilities such as alpha support or
+anti-aliasing.  Backends are modular such that any subset of backends
+is supported.")
