Filtering with more than 4 types (OSX)

[Robert Brenstein]

Since the issue of filtering has been discussed 
lately and it is pending to be fixed/improved, 
someone (Eric?) should amend the discussion of 
bug 605 to include support for more than 4 types 
(and also vote for this bug). The fact that the 
default OS procs support only 4 should not limit 
us. After all, in most other development 
environments, one simply writes own filterproc. 
We would not want that such silly restrictions 
stopped users from using Revolution, wouldn't we? 
Rev may need to write a custom proc to support 
types and extensions anyway.
