DPlot

I notice that the symbol size and the line width remain unchanged when I tile windows presented different plots. The text and numbers scale down correctly. Is it possible to fix this in the future version?

Yes. At one time I'm reasonably sure I was doing that. I'm not sure when I changed that but I can't think of a good reason not to scale everything.

From suggestion to realisation it takes only few days . David corrected scaling problem in DPlot version 1.965 and now Tiled windows look nice.
