/**
* Holefill pass: Gather background parts where foreground is present.
*
* Using the min&max CoC tile buffer, we select the best apropriate method to blur the scene color.
* A fast gather path is taken if there is not many CoC variation inside the tile.
*
* We sample using an octaweb sampling pattern. We randomize the kernel center and each ring
* rotation to ensure maximum coverage.
