Incidentally, my original vision for the "new platform" thread was for
the UI/graphics interface to be much more akin to what you see in
demos, old games, ancient systems, etc. than modern OO GUI libs, but
actually done right, and with modern features like screen size and
resolution adaptability, proper multilingual text rendering and
editing, vector graphics, etc.
If such a project is ever to progress, I think a good starting point
may be to research the good and the bad of historical practices.
Applying the principles of "library-safe code" (as yet not rigorously
defined), avoiding global state, realtime considerations, etc. could
serve to quickly filter out the faults of old school designs.
