Last I looked, and I doubt much has changed, the wx back-end required a
fair bit of love -- there was a lot of extra refresh() calls being made in
various places, most of which were unnecessary most of the time -- i.e. a
bunch of extra refreshes. I've been hoping for literally years to find the
time to go in an clean that up, but not yet....
So -- if someone can dedicate some time to clean up the wx back-end, then
it wold make sense to look into normalizing this, too. But I agree with
Eric, this is likely to be a significant job -- wouldn't tough unless
your'e ready to commit to some real work.
If it ain't broke.....
