Detailed Description
Filter to automatically buffer "margins" when iterating.
This is useful in implementing "kernel-based" spatial filters, such as low-pass, high-pass, etc. When reading, the buffer must be a window into a larger buffer to allow space for the defined margins. Note that if there is a margin added after the last row/column then the first and last tile sizes will be adjusted accordingly, resulting in a virtual shift in the tile boundaries. This may have implications when processing concurrently with other images, particularly if any images do not support efficient random access. In addition, the sequence for iterating must exactly match that specified in the call to PullBegin.
