From: Bill Spitzak <spit...@gmail.com>
This replaces settings that don't work (because the filter cannot be normalized)
with something that produces an image.
v7: First version with this. Previously you got lots of strange garbage filters
that depended on the implementation.
v10: Moved code to filter_width function
