```
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()

```

How do I take the `tile_pattern.png` image and paste that into `picture.png` and save the combined image to `modified.png`?

Given that `tile_pattern.png` is a 16x16 color image; and `picture.png` is a 128x128 color image and
I want to place `tile_pattern.png` on top of `picture.png` starting with the offset location `X=10` and `Y=10` within `picture.png`
