/**
    @class wxFont

    A font is an object which determines the appearance of text.
    Fonts are used for drawing text to a device context, and setting the appearance
    of a window's text.

    This class uses @ref overview_refcount "reference counting and copy-on-write"
    internally so that assignments between two instances of this class are very
    cheap. You can therefore use actual objects instead of pointers without
    efficiency problems. If an instance of this class is changed it will create
    its own data internally so that other instances, which previously shared the
    data using the reference counting, are not affected.

    You can retrieve the current system font settings with wxSystemSettings.
