title: cvRemap to replace cvWarpPerspective
body: <p>Below transformation is what I want to do. </p>
  
  <p>For each tile in source image, I know the coordinate of each corner, and I know the coordinate of each corresponding corner in the output image, so I can call <strong>cvWarpPerspective</strong> to warp each tile and then connect the quadrangles together to get the final output image. </p>
  
  <p>Can <strong>cvRemap</strong> do this in one transformation? If yes, how do I construct the map (mapx, and mapy) from the coordinate that I have so to pass to the cvRemap function? I've searched the EmguCV documentation but could not find a cvRemap example.</p>
