That's it. What I want is to be able to deliver graphics libraries that
don't speak to a specific type of users (namely OpenGL users, even though
I'm part of them). Moreover, this kind of library could serve as an
extensible framework to "easily" implement support for over implementations.
For example I'm currently doing quite the same kind of work to enable a
little engine I've written for PSP and then ported to PC, to run on both
with the same code.

You're probably right and anyway, the need for spatial data structures is
much more important than this need (it can even be a precondition to it).
