Gets a value indicating whether the C1DXTextLayout should NOT apply transform to the graphics when draw a vertical text using the font with NOT rotated glyphs. For example, "japan" glyphs are NOT rotated when text is drawn in vertical direction from top to bottom. Currently this property overriden in the C1.Win.Document.Util.C1GdiGraphics.C1GdiTextLayout because if StringFormatFlags.DirectionVertical is specified in StringFormat then rotation transform should NOT be applied for WinForms Graphics object.
