Cairo based backend

[Knut Petersen]

Hi everybody!

The attached patch implements a new backend based on Cairo.
To test select the desired output formats by any combination of the '--pdf', 
'--ps' and '--svg' command line options and  add '-dbackend=cairo'. The '--svg' 
option must precede the '-dbackend=cairo' option.

Features:

 * Faster than all other backends.
 * It is easy to add support for other image formats.
 * Safer than the postscript backend.
 * Files that fail with the svg backend produce valid svg  output with the 
cairo backend.
