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.
