Fix text rendering offset for raster engine on Mac
Since the bounding box returned by Core Text in smaller than the
actual glyph rendered, we have 2 pixels padding around it, as a
result, we have to leave 1 pixel above the glyph in glyph cache,
so we need to put the text origin 1 pixel lower to draw it.
