Specifies units of measurement for using in RichViewActions dialogs.
property UnitsDisplay: TRVUnits;
These units are used for entering lengths in dialog windows. For pixels, only integer values are allowed. Values measured in other units can be fractional.
Small lengths, for example paragraph spacing, are measured either in pixels (if UnitsDisplay=rvuPixels) or in points (if UnitsDisplay has another value).
Line widths can be measured in pixels even if UnitsDisplay<>rvuPixels, if PixelBorders=True.
