Testing shows that dummy1 is really a refcount, and all 4 interfaces
respond to QI with IID_IUnknown, IID_IWICBitmap, IID_IWICBitmapSource,
IID_IMILBitmap and IID_IMILBitmapSource, returning the same iface pointers.
They do not respond to other IID_IMIL* ids (that could be found in PSDK's
uuid.lib): IID_IMILBitmapLock, IID_IMILBitmapScaler, IID_IMILBitmapConverter
and IID_IMILPalette.
