Comment 11 for bug 1089406

Changes from r12012 reverted in r12137 (see comment #11 in bug #1111459).

@insaner - I'm leaving the bug assigned to you, and set the bug status to 'In Progress' for now: maybe you can find a more fine-grained solution to update only the filter effect names in the filter list on the left, without affecting other basic usage of the filter editor (bug #1111459)?

Please comment if you disagree with any of the changes.
