[Gnome-print] pixbuf print method ...

[Michael Meeks <michael helixcode com>]

	This is sort of nasty since it includes gdk-pixbuf.h in
gnome-print.h; we could of couse do the same with

	typedef struct _GdkPixbuf GdkPixbuf;

	Naughty but nice in terms of speed. It would be nice to have the
print_pixbuf API to stop people forgetting alpha and to reduce lines of
code count in my eog bonobo component.

	Regards,

		Michael.
