Everything in Impeller is theoretically treated as if being drawn to layers of infinite size. Without this change, there's a coverage leak that occurs in some filters due to the customizable sampling mode. I should be able to get rid of this 1 pixel padding by refactoring the way we do sampling in the filter inputs (we already have most of this infrastructure in place), but this is a correct, safe, and not-that-expensive solution for the time being.
