         * WARNING ! Due to a known bug in PHP 4.3.2 this script is not working well in this
         * version. The sharpened images get too dark. The bug is fixed in version 4.3.3.
         *
         * From version 2 (July 17 2006) the script uses the imageconvolution function in
         * PHP version >= 5.1, which improves the performance considerably.
         *
         * Unsharp masking is a traditional darkroom technique that has proven very
         * suitable for digital imaging. The principle of unsharp masking is to create a
         * blurred copy of the image and compare it to the underlying original. The
         * difference in colour values between the two images is greatest for the pixels
         * near sharp edges. When this difference is subtracted from the original image,
         * the edges will be accentuated.
         *
         * The Amount parameter simply says how much of the effect you want. 100 is
         * 'normal'. Radius is the radius of the blurring circle of the mask. 'Threshold'
         * is the least difference in colour values that is allowed between the original
         * and the mask. In practice this means that low-contrast areas of the picture are
         * left unrendered whereas edges are treated normally. This is good for pictures of
         * e.g. skin or blue skies.
         *
         * Any suggenstions for improvement of the algorithm, expecially regarding the
         * speed and the roundoff errors in the Gaussian blur process, are welcome.

         *
         * @param image $img the GD format image to sharpen. This is not a URL string, but
         *   should be the result of a GD image function.
         * @param int $amount the strength of the sharpening effect. Nominal values are between 0 and 100.
         * @param int $radius the pixel radius of the sharpening mask. A smaller radius sharpens smaller
         *   details, and a larger radius sharpens larger details.
         * @param int $threshold the color difference threshold required for sharpening. A low threshold
         *   sharpens all edges including faint ones, while a higher threshold only sharpens more distinct edges.
         * @return image the input image with the specified sharpening applied.
