/*
    Quasi-Modal Mode Explained:
 
    The gtk calls in wxDialog::ShowModal() cause event routing problems if that
    modal dialog then tries to use KIWAY_PLAYER::ShowModal().  The latter shows up
    and mostly works but does not respond to the window decoration close button.
    There is no way to get around this without reversing the gtk calls temporarily.
 
    Quasi-Modal mode is our own almost modal mode which disables only the parent
    of the DIALOG_SHIM, leaving other frames operable and while staying captured in the
    nested event loop.  This avoids the gtk calls and leaves event routing pure
    and sufficient to operate the KIWAY_PLAYER::ShowModal() properly.  When using
    ShowQuasiModal() you have to use EndQuasiModal() in your dialogs and not
    EndModal().  There is also IsQuasiModal() but its value can only be true
    when the nested event loop is active.  Do not mix the modal and quasi-modal
    functions.  Use one set or the other.
 
    You might find this behavior preferable over a pure modal mode, and it was said
    that only the Mac has this natively, but now other platforms have something
    similar.  You CAN use it anywhere for any dialog.  But you MUST use it when
    you want to use KIWAY_PLAYER::ShowModal() from a dialog event.
