	If I were you I'd send the data as a sequence<octet> since this is a
specially optimised case inside the ORB (for speed). Also, you can do:

CORBA_sequence_CORBA_octet seq;

seq._buffer = gdk_pixbuf_get_pixels (pixbuf);
seq._length = get_rowstride * get_height;

	Of course, you'll prolly want to embed that in a struct to parse the
width, height, depth, rowstride information as well.

	Really libbonoboui should have some helper here I guess ( in fact
libbonobo should have it and gdk-pixbuf should not be tied to gtk+, but
... ;-).

	HTH,

		Michael.
