 *  pixBackgroundNormSimple()
 *
 *      Input:  pixs (8 bpp grayscale or 32 bpp rgb)
 *              pixim (<optional> 1 bpp 'image' mask; can be null)
 *              pixg (<optional> 8 bpp grayscale version; can be null)
 *      Return: pixd (8 bpp or 32 bpp rgb), or null on error
 *
 *  Notes:
 *    (1) This is a simplified interface to pixBackgroundNorm(),
 *        where seven parameters are defaulted.
 *    (2) The input image is either grayscale or rgb.
 *    (3) See pixBackgroundNorm() for usage and function.
