Thanks for the information; I'd seen the article, but will look at it again.
It might be best if an initial implementation, at least, were as portable as
possible (e.g., using OpenGL to do simple things like projective
transformations for alignment).  Ideally, the implementation would also be
independent of X, or any other particular display system, but I haven't looked
at the details of what this would involve, so I'm not sure whether this is
easily done.  If there is to be dependence on a display system, however, X
would seem to be the most obvious choice.
