Yeah, it's an omission on my part, thanks.

BitmapImpl_Create creates its own internal buffer for a WIC bitmap bits,
while 'buffer' is used to store GDI bitmap bits. The only way to access
WIC bitmap bits from ComponentFactory is using IWICBitmapLock (to not
break the object separation/implementation detail rules). And 'buffer'
is reused twice: once for GDI image bits, and next time for the GDI mask
