Its customary to make a function return NotImplemented in Gdiplus, if its just a dummy function that does nothing and returns. But .NET seems to check for this and throw an exception, crashing the program anyway.
See bug http://bugs.winehq.org/show_bug.cgi?id=12951 for details, but originally a program crashed because GdipNewPrivateFontCollection was just a stub. After the function was created, it still crashes because it returns "NotImplemented", rather than "Ok". IIRC, we return "NotImplemented" for some debugging reason, but if the goal of Wine is to run Windows applications, should we just go ahead and return "Ok" so that .NET apps don't freak out?
Of course in a perfect world, we wouldn't have to fake a return code, but until that time comes do people have opinions one way or another?
