 DISPLAY_IMAGE
        Colour/greyscale image display in data coordinates.

 Usage:
        display_image, zin, xin, yin, xrange=xrange, yrange=yrange, $
        zrange=zrange, $
        colour_range=colour_range pixel_size=pixel_size

 Arguments:
        zin     float   input   The data to be displayed
        xin     float   input   The X coordinates of the data.
        yin     float   input   The Y coordinates of the data.

 Keywords:
        zrange          float   input   The range from "black" to "white"
        no_dummy                input   If set then don't do a dummy
                                        plot to set the scaling.
        colour_range    int     input   The range of colour indices to use.
        pixel_size      float   input   For devices with scalable pixels, the
                                        size of a displayed pixel.
        nan_colour      int     input   Set a colour for invalid data.

        Also accepts any keyword that PLOT will accept. (though things
        like psym won't do anything).

 Notes:
        Currently doesn't work in a !p.multi environment.
