gnome_canvas_item_rotate?

[sottek <sottek quiknet com>]

All,
  What happened to gnome_canvas_item_rotate? It is in gnome-canvas.h
but not in gnome-canvas.c. Was this just an oversight, or did you want
it
removed? Anyway, since it seems useful and was trivial to do, I included
it here.

Note that I'm not sure this works for imlib stuff (perhaps only with
AA?),
but it works for the GdkPixbuf which is a good reason to convert anyway
:)
