*MarginMM are applied only on paper/print preview.

*Margin are applied both on paper and in editor.

There is a picture showing difference between these margings at the bottom

of the help topic about TRVPrint.

Look at it - a picture worths a thousand words.

You can calculate value by formula:

(size in screen pixels) = (size in inches) * Screen.PixelsPerInch.

// when printing, RichView will keep size in inches - it recalculates

// size in pixels according to printer and screen resolution

(size in millimeters) = (size in inches) * 127 / 5

However, there is a problem.

If another user will open this document on computer with another

Screen.PixelsPerInch value,

distance in inches will not be preserved.

I'll try to solve this problem in the next version.
