The last filters that had not been ported to the new filtering infrastructure have been ported and their documentation updated. All filters now use window specifications (instead of vector of pointers). The misleading filter argument "index" (for parameter type) has been renamed as "param" for all filters. The use of "unsigned int" for looping over vectors has been replaced by "size_t". The old "soft" behavior for the filters has been restored (ie: if not soft, a point that can not be checked by the filter is deleted).

A few more "consts" have been added.
