Um, I'm planning to break this soon. We need additional decoders for
d3dx dlls, and I've been told not to make a new dll for them. That
means they either have to go into windowscodecs or individual d3dx
dll's, and putting them in windowscodecs seems to make more sense.

Since native won't have these decoders, it will break builtin d3dx.
