public static Nullable<SimpleTextGlyphRunMode> GetGlyphRunMode( DependencyObject d )
Note: GlyphRuns are significantly faster than FormattedText. However, they don't support ligatures or TextOptions.TextFomrmattingMode of 'Display'. The inherited attached GlyphRunMode and properties are used to determine this behavior.
Regardless of these settings GlyphRuns will not be used if FlowDirection is 'RightToLeft' or the text contains characters that do not map to a glyph in the current font.
