title: In python, using the cv2 library; how can I tile one image into a second image?
body: <pre><code>import cv2
  tile = cv2.imread('.\tile_pattern.png')
  h,w = tile.shape[:2]
  photo = cv2.imread('.\picture.png')
  # ???? do something to copy tile onto photo @ x=10 y=10
  # COPYIMAGE( tile, 0:0, h:w, photo, 10:10)
  cv2.imshow('image', photo)
  cv2.imwrite('./modified.png', photo)
  cv2.waitKey(0)
  cv2.destroyAllWindows()
  </code></pre>
  <p>How do I take the <code>tile_pattern.png</code> image and paste that into <code>picture.png</code> and save the combined image to <code>modified.png</code>?</p>
  <p>Given that <code>tile_pattern.png</code> is a 16x16 color image; and <code>picture.png</code> is a 128x128 color image and
  I want to place <code>tile_pattern.png</code> on top of <code>picture.png</code> starting with the offset location <code>X=10</code> and <code>Y=10</code> within <code>picture.png</code></p>
