richedit: Documented paragraph border widths are in points not pixels.
The border widths documented by msdn are in points which are 72 dpi, which is not equivalent to pixels (normally 96 dpi). I pre-converted all the border widths to 96 dpi resolution since this avoids needed to store fractions, and often avoids the need for convertion to the displays resolution.
