 We are working with virtual reality videos and it is not uncommon for
 those videos to be bigger than 4096x4095.
 Ticket [ticket:6795] helped a lot but we have more and more videos in a
 very high resolution.
 Is it possible to remove resolution limits completely from minterpolate
 filter?
 How to reproduce:
