* Structure describing the size zero point padding compensation buffer.

* number of unique application of filter over input spatial where filter
* overlapped the padding need for calculating unique zero point padding
* compensation of given case. Pad variables represents number of unique
* zp padding compensation values resulting from participation of a given type
* of padding (example top padding) over a given axis (example h). Mid points
* over given axis represents compensation resulting in the absence of padding
* over given axis, but where padding over other axis exists. Example: 2D: conv:
* mid_point_w = true, where filter overlaps top padding, but not right and left
* padding. Spatial filter w size fits in w range of input image.
