System.Drawing.Icon is partly incompatible with Mono's implementation

[QianNangong]

The program is
https://ppmforums.com/download.php?id=29787
It works fine with some layout glitches when used with Mono's implementation, but it won't run with sysdrawing-coregraphics, it will throw such an exception.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Thanks for reporting it. We will give it a try and see what the issue is. The Mono code does the icon parsing in managed C# code while this implementation depends on the underlying CoreGraphics APIs. We recently had some examples of slightly malformed icons that failed to parse and it's possible the code may need some further tweaking.
