world vs. canvas coordinates in comment in gnome-canvas.h

[Darin Adler <darin eazel com>]

[ I asked this yesterday on gnome-list. No answer, so I'm moving up the
  food chain. ]

The comments for the x1, x2, y1, and y2 fields of GnomeCanvasItem say that
these are in world coordinates. But it seems clear from the actual code that
they are in canvas coordinates. Should this be corrected in the header file
or am I missing something?
