/*
 * FUNCTION
 *      mlib_ImageAndNot   - andNot two images  (C version)
 *
 * SYNOPSIS
 *      mlib_status mlib_ImageAndNot(mlib_image       *dst,
 *                                   const mlib_image *src1,
 *                                   const mlib_image *src2);
 *
 * ARGUMENT
 *      dst     pointer to destination image
 *      src1    pointer to first source image
 *      src2    pointer to second source image
 *
 * RESTRICTION
 *      The src1, src2, and dst must be the same type and the same size.
 *      They can have 1, 2, 3, or 4 channels.
 *      They can be in MLIB_BYTE,
 *      MLIB_SHORT, MLIB_USHORT, MLIB_INT or MLIB_BIT data type.
 *
 * DESCRIPTION
 *      AndNot two images for each band:  dst = src1 & (~src2)
