I see, thanks for the explanation. Under Windows IWICBitmapScaler_QueryInterface
and IMILBitmapScaler_QueryInterface return the same interface for IID_IUnknown,
but that interface is neither IWICBitmapScaler nor IMILBitmapScaler. Same thing
I observe with IWICBitmap and IMILBitmap. Probably the interface returned is
some base class that forwards its methods to one of IWIC or IMIL classes.

I guess that changing IMILBitmapScaler_QueryInterface to return the same
interface as IWICBitmapScaler_QueryInterface does is the right thing to do.
