[LyX/master] Let math preview adapt to surrounding font color

    Let math preview adapt to surrounding font color
    
    This is done via adding \color{} in preview LaTeX source.
    Note that dvipng's -fg setting applies to all preview snipets
    so inappropriate to use for colorization of individual math
    symbols.
