Add more debugging output.

2002-11-12  Tor Lillqvist  <tml@iki.fi>

	* pango/pangowin32-fontcache.c (free_cache_entry,
	cache_entry_unref, pango_win32_font_cache_load): Add more
	debugging output.

	* modules/basic/basic-win32.c (uniscribe_shape): Plug memory leak:
	Free return value from pango_win32_font_logfont(). Call
	pango_win32_font_cache_unload() for the hfont returned from
	pango_win32_font_cache_load() after using it.
