/**
* An <code>OpImage</code> implementing the "Add" operation as
* described in <code>com.lightcrafts.mediax.jai.operator.AddDescriptor</code>.
*
* <p>This <code>OpImage</code> adds the pixel values of two source
* images on a per-band basis. In case the two source images have different
* number of bands, the number of bands for the destination image is the
* smaller band number of the two source images. That is
* <code>dstNumBands = Math.min(src1NumBands, src2NumBands)</code>.
* In case the two source images have different data types, the data type
* for the destination image is the higher data type of the two source
* images.
*
* <p>The value of the pixel (x, y) in the destination image is defined as:
* <pre>
* for (b = 0; b < numBands; b++) {
* dst[y][x][b] = src1[y][x][b] + src2[y][x][b];
* }
* </pre>
*
* <p>If the result of the addition overflows/underflows the
* maximum/minimum value supported by the destination image, then it
* will be clamped to the maximum/minimum value respectively. The
* data type <code>byte</code> is treated as unsigned, with maximum
* value as 255 and minimum value as 0.
