John, All this brings to mind something I wanted to bring up anyway: we have a proliferation of backends, and occasional requests for more--are there any we can simply drop now, or soon? For example, gd? And what are the prospects that several backends could be consolidated via cairo? And/or via more extensive subclassing?
I am worried that we are increasingly going to get into trouble with lack of up-to-date support for all these backends. Major improvements sometimes depend on backend changes, and the more backends we have that lack active maintainers, the harder this gets; and the worse for users, as features work on one backend but break on another.
