Hello,

Actually that one is probably not needed. When a stub exception is continued,
execution will proceed into the next stub defined for that dll and cause
another exception, it doesn't mean that the app called that function.
--- quote ---

Maybe you misread ... it's not the infamous "unimplemented function" exception.
The stub returns gdiplus specific "not implemented" code which gets thrown as
CLR exception by .NET runtime callable wrapper.

--- snip dlls/gdiplus/font.c ---
GpStatus WINGDIPAPI GdipNewPrivateFontCollection(GpFontCollection**
fontCollection)
{
    FIXME("stub %p\n", fontCollection);

    if (!fontCollection)
        return InvalidParameter;

    return NotImplemented;
}

Later GdiplusNotificationHook proc is explicitly queried and called by .NET
CLR, most likely to propagate/pass initialization/shutdown events.

Small stubs for the gdiplus NotificationHook/NotificationUnhook procs should be
sufficient.

--- snip ---

Regarding the initial bug ... it seems all gdiplus functions dealing with font
collections are just stubs that need to be worked on.
