There would some benefit if there is a common class "Filter" for all filters
or if you could directly manipulate the filter info that way. I'm not sure
yet how to do it the best way, but both features would be quite handy for
other XOTcl structures as well.


PS: another issue: there were some requests for new info options on this list.
right off the head:

- list of all procs defined for an object (procs + all instprocs up the
  heritage order)
- list of all mixins (mixins+instmixins) for an obj
- list of all filters (filters+instfilters) for an obj

Perhaps return certain infos conditionally as ligthweight objects ...

Were/are there any other suggestions?
