    Improve appearance of small-sized mathtext. · f5ee8c17

    The alpha mask returned by Matplotlib for mathtext renderings
    appears very dim when font size is small.
    
    This patch uses the same trick in MatplotlibMathTextUtilities
    as FreeTypeTools, which doesn't blend RGB values when the
    background alpha == 0. This gives a bolder appearance to the
    text, like it was before the text background color options
    were added.
    
    Also clamped the tprop opacity setters to [0., 1.] and updated
    a baseline that had small mathtext.
