‘Weston 3-field’ interlace to sequential converter.

This improves on the image quality of simple vertical filtering by taking high vertical frequencies from adjacent fields. It is probably as good as you can get without motion compensation or other complicated techniques.

The mode config selects one of two filter sizes. Mode 0 has a vertical aperture of 5 lines, mode 1 has a vertical aperture of 9 lines.

Config
mode	int	Filtering mode. Can be set to 0 or 1.
topfirst	bool	Top field first.
