title: warpPerspective and warpAffine is not working for large images, height>32k
body: <p>I am trying to warp 16-bit satellite images. I have Panchromatic images. My reference image is 8192x81920 pixels, and a Red channel image is 4096x40960 pixels. When I use <code>warpAffine</code> or <code>warpPerspective</code>, pixels with row values greater than 32767 are not warped correctly. Is this a simple bug? May I correct it with change of variable types?</p>
  
  <p>I have checked <code>warpPerspectiveInvoker</code> function but could not see an easy fix.</p>
