public LineMetricsImpl(int len, float[] metrics, float[] _baselineData)Creates LineMetricsImpl object from specified parameters. If baseline data parameter
is null than {0, (-ascent+descent)/2, -ascent} values are used for baseline offsets.
numChars = len;
ascent = metrics[0]; // Ascent of the font
descent = metrics[1]; // Descent of the font
leading = metrics[2]; // External leading
height = metrics[0] + metrics[1] + metrics[2]; // Height of the font ( == (ascent + descent + leading))
