Interesting. The "movable and nondiscardable" I could
believe. Does it really make a difference, has it been
noticed to cause problem otherwise.
However, regarding fDeleteOnRelease--it means that
the Global Handle will be deleted when IStream is
released, which makes pefect sense, so OleRelease is
fine. Unless, that is, GdipCreateBitmapFromStream will
call release on the passed interface. Is that the case?
