The last methods are utility methods for setting the texture, either from a texture
name that must be loaded from the resource cache, or a texture that is already
loaded:

if (texture)

shared_ptr<D3DTextureResourceExtraData11> extra =
static_pointer_cast<D3DTextureResourceExtraData11>(texture->GetExtra());
