How to access neighboring pixels using Mat::forEach?

Feature addition!

It would be great if Mat::forEach method allows us to access the neighboring pixels for interpolation! As per this Question, the current implementation of Mat::forEach method will not allow us to access the neighboring pixels.

Any help regarding this feature addition will be so helpful!

A similar implementation is the cuda kernal functions, where we can access any pixels from a single kernel thread! My idea is to reuse the cuda kernels code for CPU with minimum effort!
