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

Expected:

  The first parameter passed to the callback is the pattern

Actual:

  Some different pattern is passed and it is dead, so doing anything with it
crashes.</pre>
