    pangowin32-fontmap.c: Add an Emoji font family
    
    Add an Emoji font family that maps to the following fonts in this order
    (by fallback):
    Segoe UI Emoji
    Segoe UI Symbol
    Segoe UI
    
    This will enable Emoji to be displayed correctly in GTK+ apps (without
    the use of FontConfig) on Windows Vista and later, providing that one
    of the aforementioned fonts are installed.
    
    Note that this only enables Emoji display (*not* colored ones) as
    achieving colored Emoji requires PangoWin32 and Cairo to be ported to
    Direct2D and DirectWrite from Uniscribe and GDI, as Uniscribe and GDI
    does not support colored Emoji.
