Summary:
To force the image x coordinate to be P and the image y coordinate to be Q, you hook up nodes to the offsets as
U_Offset = U - P
V_Offset = V - Q
And now you have total control over the coordinate, independent of the U and V values. You are now free to do anything you want with the coordinates to look up whatever color you want at (P, Q)
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
