Original change's description:
> Update lockTextureProxy to return mipped proxys if mipping is requested.
> 
> We will either create a new mipped surface from scratch, or just create
> the base layer and copy that into the mipped surface. We then defer the
> creation of the rest of the mips to the GPU.
