2004-12-05  Tor Lillqvist  <tml@iki.fi>

	* gdk-pixbuf-animation.c
	* gdk-pixbuf-io.c
	* io-xbm.c
	* io-xpm.c
	* make-inline-pixbuf.c
	* queryloaders.c: Use gstdio wrappers. Document that file names
	are in the GLib file name encoding.

	* gdk-pixbuf-csource.c
	* queryloaders.c: On Windows, convert command line arguments and
	environment variable values from locale encoding to UTF-8.

	* queryloaders.c: On Windows, use wide character API when
	available.

	* Makefile.am
	* gdk-pixbuf-core.h
	* gdk-pixbuf-io.c
	* gdk-pixbuf-animation.h
	* gdk-pixbuf-animation.c: Like in GLib, for DLL ABI stability on
	Windows, add binary compatibility versions of functions that take
	file names as arguments. They use the system codepage, not GLib
	file name encoding (which is UTF-8 on Windows). Use #defines to
	make newly compiled code use the "real" functions that use the
	GLib file name encoding scheme.
