<remarks>
This enumeration supports a bitwise combination of its member values.
If a single filter is chosen, then that filter will be used for every row.
If multiple filters are chosen, then a heuristic will be used to guess
which filter will encode smallest, then apply that filter. This happens
on a per row basis, different rows can use different filters.
</remarks>
<remarks>
Using a single filter (or less filters) is typically faster. Trying all of the filters may help minimize the output file size.
