[pygtk] pygtk compiled with numpy for win32

[Craig Warren]

Thanks, I'm currently using gtk.gdk.pixbuf_new_from_data() after converting the numpy array using to_string. Unfortunately I'm updating largegtk.gdk.pixbuf_new_from_array would overcome this bottleneck. I'll try using struct.pack_into(..) and see if this is faster?
