Add pango_win32_os_version_info variable, an OSVERSIONINFO struct.
2002-03-17 Tor Lillqvist <tml@iki.fi>
* pango/pangowin32-private.h: Add pango_win32_os_version_info
variable, an OSVERSIONINFO struct.
* pango/pangowin32.c: Initialise it.
* pango/pangowin32.h: Set _WIN32_WINNT to 0x0501 before including
<windows.h> to get the ClearType-related macros defined (if recent
enough headers are used).
* pango/pangowin32-fontcache.c (pango_win32_font_cache_load): Set
desired font quality to CLEARTYPE_QUALITY if on XP (or later), and
the system settings ask for ClearType.
