I asked Alexandre to wait until I had more time to understand/test this patch.

It seems you've introduced a problem with scaling (see attached test
program and screenshot). I think that MeasureString is working
correctly in this case, and DrawString/MeasureCharacterRanges are
wrong.

This sort of problem would be less likely if the logic were in
gdip_format_string.
