Library hierarchy.

Hi, it is quite late to complain about the hierarchy of the new hierarchical library. But I think I should do it eventually. There is a path Graphics.UI which I think is conceptually wrong. User Interfaces are not a subset of Graphics but rather the other way round. I don't know if it makes sense to do graphics without interacting with the user, if not then I would expect the hierarchy to look more like this: UI.GUI -- GUI stuff like ObjectIO or CGA UI.Graphics -- stand-alone graphics stuff like HOpenGL UI.Joystick -- An example of a non-graphical user interface I guess for compatibility, Graphics has to stay. Could we have a top-level UI branch so the CGA can go in there? Axel.
