[Mono-winforms-list] Graphics.FromHwnd(IntPtr.Zero) not working

[Carlos Alberto Cortez]

Hello,

This method is defined basically to retrieve available information in the
Graphics instance, not to do actual draw work on the screen (this could be
accomplished by a different way, but it would be system specific, as nothing
like that appears in the winforms api).

Carlos.
