Is it time to have the discussion about dropping the MacOS backend?
I know an incredible amount of top quality developer time has gone into it,
but in truth it is not up to the *Agg backends and without another massive
amount of work, never will be. Not to mention the drag that having YAB (yet
another backend) to maintain and support adds.
Deleting the MacOS backend doesn't mean the end of its life - if somebody
cares enough they will probably set up a repo and maintain it themselves,
but I can think of a million and one things I'd sooner have matplotlib
developers working on than getting the MacOS backend upto the *Agg standard.
Thoughts?
