Export this symbol for loading an XPM from memory.

1999-10-22  Havoc Pennington  <hp@pobox.com>

* src/io-xpm.c (image_load_xpm_data): Export this symbol for
loading an XPM from memory.

* src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): New
function, loads pixbuf from xpm data
(image_handler_load): Add g_return_if_fail() to ensure the same
module isn't loaded twice. Add g_module_symbol() to scan for XPM
loader function.
