example program

I'm currently trying to bind raster source patterns in pycairo and hitting some
problems I don't understand.

See the example program:

1) Set a callback through cairo_raster_source_pattern_set_acquire
2) Wait until the callback is called


  The first parameter passed to the callback is the pattern


  Some different pattern is passed and it is dead, so doing anything with it
