Actually, most of it belongs in optional Protocols - which are pretty
similar to OpenGL extensions, except that they aren't supposed to
ever end up in the compulsory core set of Protocols. (The idea is to
keep these Protocols on a higher level than the basic plugin/host
interaction, so that the implementation of those Protocols can be
moved out into "helper plugins" that could be reused.)
Now, I'm only beginning to run actual MAIA "plugins", so there's
probably some more "moving things around" to do before it's time for
an initial release of the API. I need to look at some actual plugin
code before I can sort out where some things really belong. (Trying
to get a good API complexity/flexibility ratio.)
