/*!
    \brief Owner-Draw Default Button is a base class for owner-draw buttons that provides basic
    support for default state handling.

    Derived class can indicate the default state when appropriate simply by calling
    COddButton::IsDefault method to determine the default state and using
    any visual effect (e.g. a thin black frame around the button) when it becomes default.

    \note A special static method COddButton::SetDefID can be used to set the default button
    for the dialog to work around the problems with using a CDialog::SetDefID described in MS kb Q67655
    (<A HREF="http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q67655&">
    HOWTO: Change or Set the Default Push Button in a Dialog Box
