I like the idea of having a new option, too.  The option name "reinit_filter" doesn't imply anything
about "scaling"... it's just a side-effect.  That is, reinit_filter could cause other filters to behave
differently too, right?  So an explicit option to enable/disable auto scale would imply a more
obvious expectation to the user.
