Re: [v2 PATCH] include/wincodec.idl: Stop redefinition of ID2D1Image

[Vincent Povirk]

Why can't we handle this the way that d2d1.idl does? It doesn't
include wincodec.idl, but it declares the interfaces it uses from
there.

I know the Windows SDK doesn't do that, but that's probably because
the SDK headers are weird and don't declare the d2d1 interfaces in an
idl.
