    If you want fix linespace bug when mix Chinese & English, set leading = -100 and maximumLineHeight = minimumLineHeight = font.lineHeight.
    Make sure TTTLabel draw after Cell draw, and make sure setNeedsDisplay every time. Such as tableview reuse.

    Add property minimumLineHeight and maximumLineHeight.
    Remove all setNeedDisplay. If you want update, do this manual.
    Fix the bug when mix Chinese and English lineheight error. Now draw line
    offset y as -(font.descender+line descent). It's offset from label baseline.
