* Properties: a dimension's text height, arrow size, overall scale and precision (#1259) The Properties palette showed only a dimension's text override and style, so the only way to change its text height was a new dimension style. It now shows Text height (DIMTXT), Arrow size (DIMASZ), Dim scale overall (DIMSCALE) and Precision (DIMDEC) with the values the dimension draws with. Editing one sets a per-dimension override (DIMOVERRIDE) on the selected dimensions, as AutoCAD's Properties palette does; the style is left alone. properties.set takes textHeight, arrowSize, dimScale and precision for dimensions and refuses bad values before changing anything.
