/**
 * Function:  omxIPBM_Copy_U8_C1R   (4.2.1.1.2)
 *
 * Description:
 * Copy pixel values from the ROI of the source image referenced by the 
 * pointer pSrc to the ROI of the destination image referenced by the pointer 
 * pDst. The source ROI should not overlap the destination ROI within the same 
 * image buffer. 
 *
 * Input Arguments:
 *   
 *   pSrc - pointer to the source ROI 
 *   srcStep - distance in bytes between the starts of consecutive lines in 
 *            the source image 
 *   dstStep - distance in bytes between the starts of consecutive lines in 
 *            the destination image 
 *   roiSize - size of the source and destination ROI in pixels 
 *
 * Output Arguments:
 *   
 *   pDst - pointer to the destination ROI 
 *
 * Return Value:
 *    
 *    OMX_Sts_NoErr - no errors detected 
 *    OMX_Sts_BadArgErr - bad arguments detected; at least one of the 
 *              following is true: 
 *    -   pSrc or pDst is NULL 
 *    -   srcStep or dstStep is less than or equal to zero 
 *    -   roiSize has a field with zero or negative value.
