memory leaks on pango examples

[august <august alien mur at>]

hi,

	I'm trying to debug some of my code (which is based on the example
	code provided by pango), and came across a bunch of memory leaks.
	I'm still new to valgrind, so can anyone explain to me why there are
	leaks with:
		
	valgrind --leak-check=full ./cairosimple blah.png

	where "./cairosimple" is the example program provided in the pango
	source dir.



	thanks -august.
