The CoreText implementation dropped the support of DXArray more exactly ignored the values provided in it. And try to approximate the result by assuming that all it does is full justification... which is not quite right This ut the feature back, buy handing the glyph drawing directly, rather than defering to CoreText CTLineDraw to control the position of each Glyph Change-Id: Ibe0cfe789d3be441c012d8ac1104d939204a591c
