Lots of code, C and Lisp, does that kind of calculation.In what sense can they be simplified if we used absolute scaled coordinate in Lisp as you say?Then they wouldn't need to be changed at all.Even with absolute unscaled, they DIDN'T need any changes in the platform independent part.
That would require unscaled everywhere, even in pos-x-y, window sizes, font sizes and so on. I didin't think that was your suggestion.
Window system APIs requires us to specify absolute unscaled coordinates when creating windows or popup menus, so some conversions are necessary anyway.That is the job of the platform specific code.So you agree that changes are necessary in the platform specific part regardless of scaled or unscaled when we support scaling factor?
I've said that from the start.
Again, if we used absolute scaled coordinates to specify `left' and `top' frame parameters, we could only place the frame to the position whose coordinates are multiples of the scale factor.
As I said earlier, special functions to deal with that for those that care. Jan D.
