Always turn on anti-aliasing.

	* pango/pangowin32-fontcache.c (pango_win32_font_cache_load):
	Always turn on anti-aliasing.

2001-11-21  Tor Lillqvist  <tml@iki.fi>

	* pango/testfonts.c: Fix a couple of bugs, update for current
	Pango API. It's not completely clear to me what the program is
	supposed to do with the command line args. It does load a
	matching font, but does nothing with it. It then always lists
	*all* font families, and renders a string in each. This causes
	a huge image with associated swapping to death if you have
	lots of fonts... I added a restriction, only the first 10
	fonts are rendered.
