    @disucssion
    Cocoa has three classes which interact to form the font system:

    NSFont: Represents a specific font (e.g. Times-Bold) at a specific size
    with specific attributes.  That is, it's basically like this class.
    Notably, it doesn't hold an underlined flag, so this class does.
    Available on all OS X versions.

    NSFontManager: Fairly broad controller class which ties together the
    model (NSFont) with the view (NSFontPanel).  We are ignoring NSFontPanel
    in this discussion.  NSFontManager is actually a little broader than just
    a controller though.  It's also the traditional way of mutating fonts
    and asking for a font with a certain family and certain attributes.
    For example, you can use NSFont's factor methods to create a font named
    @"Times-Roman" then use NSFontManager to imbue attributes like italic and
    bold.  You might do this if, for instance, you already have times at the
    Roman weight but want to make it bold.

    Alternatively, you can use NSFontManager to ask for a font in the @"Times"
    family with the bold attribute.

    NSFontManager is available on all OS X versions.

    NSFontDescriptor: Added in OS X 10.3.  Prior to this there was no specific
    class to represent all of the attributes of a font.  Instead, a regular
    NSDictionary was used with a set of well-defined keys.  Unfortunately,
    there was no method accepting the attributes dictionary, only a method
    to retrieve it from an NSFont.  That meant that in order to create
    a new font by imbueing certain attributes like Bold one would need
    to use the specific method in NSFontManager to do so.

    The NSFontDescriptor class, on the other hand, has factory methods which
    can create a new font descriptor with an attributes dictionary as well
    as mutate (by copy) an existing font descriptor using attributes from
    an attributes dictionary.

    In theory, most of what can be done using NSFontDescriptor can just as
    well be done without it.  NSFontDescriptor is basically just a shell
    around an NSMutableDictionary with well-defined keys.


    Getting back to the broad overview, font matching is one of the weaker points
    in Cocoa's API and NSFontDescriptor is the easier to use solution.

    That said, it's not impossible to implement font matching without it. For instance,
    if you have a family name and want to list available variants (e.g. Bold, italic,
    underlined) then you can ask NSFontManager for availableMembersOfFontFamily:.

    The problem is that you can either match on family name or on font attributes
    but not on both.  To match both you have to do one then the other.
    NSFontDescriptor allows you to get a list of fonts matching both a family name
    and a particular set of attributes.  Furthermore, the attributes instead of
    being flags as in NSFontManager are instead well-defined keys in a dictionary.

    The only way to get that behavior without NSFontManager is to pare down the
    list as much as possible using the classic NSFontManager methods and then
    to instantiate each font in the list and match on each font's afmDictionary.

    A reasonable guess is that that's probably more or less exactly what
    NSFontDescriptor does internally.

/*! @discussion
    Due to 2.8 ABI compatibility concerns we probably don't want to change wxNativeFontInfo
    although this may be unfounded because this class is supposed to be internal as is
    wxNativeFontInfo so anyone who subclassed it or created one without going through
    wxFont should expect what they get (i.e. horrible breakage)
    There's a concern that wxFontRefData was in the public header when 2.8 shipped so
    it's possible that someone did subclass it to get better font behavior.

    For right now, the plan is to write it strictly ABI compatible with 2.8 and eventually
    to enhance it in trunk to accurately represent font attributes as Cocoa sees them.

    I'd like to let at least one 2.8 release go out the door and get feedback as to whether
    this is going to be a problem or not.  If so, we'll keep it strictly ABI compatible.
    If not, we'll update it.
