Represents a single filter pass in the scaling graph.
Each filter will read from some previous pass's output, and write to a buffer associated with the pass (or into the final output image).

| sws_filter_run_t SwsPass::run |
Filter main execution function.
Called from multiple threads, with the granularity dictated by slice_h. Individual slices sent to run are always equal to (or smaller than, for the last slice) slice_h.

Called once from the main thread before running the filter.
Optional. out and in always point to the main image input/output, regardless of input and output fields.
