What feature would you like to be added?
imageDstOrigin is confusing when a destination image is a sub-image. imageDstOrigin actually returns the origin position of the sub-image. This is correct, but this is useless when you want to calculate a relative position from the 'entire' destination position.

What about adding a new function to return the origin position of the entire destination image?
Another suggestion is, stop atlas-ing destination images (again) so that the origin position is always (0, 0).
Why is this needed?
To avoid confusion.
