This is a suggestion: It's probably appropriate to annotate the lines
in ui.theme.css to the effect that "filter:" clauses are, for now, IE-
only hacks.
In other words, annotate the lines containing the following
filter:Alpha(Opacity=NN)
Rationale: I think it's generally recognized and accepted best
practice to annotate CSS hacks or, to be more charitable, annotate
anything we do in CSS that isn't standard. This will save some goose-
chasing by folks seeking to override jQuery-UI's very pale (too pale?)
ui-state-disabled visuals.
