Text Attributes Tests:\n\n\
Top:      Red 2D text showing various kinds of alignment: \n\

          Markers are drawn on the text point for each text primitive.\n\
Center:   1. Red 2D text rendered using bundled attributes.\n\
             (color and spacing)\n\
          2. Text drawn in blue\n\
          3. 2D text rendered with 2 different up vectors: \n\

Mid-Left: 2D text drawn in 4 different paths: \n\

Bottom:   1. 2D text drawn with char height: -0.02, 0, 0.04.\n\
