I am willing to do that, but let me now explain the problem, which triggered
BTW, I'm also on linux and under linux I face the same trouble.
I had to optimize a very complex graph which was representing some
underlying data structure.
1) It required DIN-A3 (bigger than screen)
2) It required programming and use of strwidth(), as I needed an automated
way to transform data-to-graph
3) It required interacting based on locator() to change the underlying data
basis and replotting data-to-graph
4) (Thus) It required seeing the whole device during interaction, thus
probably scroll_bars/zooming would not help.
5) It required some fine tuning (text wrapping, font size and other
parameters) ON SCREEN before printing.
E.g. there was text surrounded by boxes, and the text had to fit within
boxes tightly. Relatively to the DIN-A3-device the text was small, but it
had to be that size to get a realistic impression of space needs.
Does my point get clear now?
However, beside this particular problem, I'm convinced that a proper
seperation between device features and window features would be very
