Suppose you want to store the u32 value of a created stdweb object that wraps a Reference. For me, I am working with WebGLTexture objects. You can get the u32 value out like this

        let texture = try_opt(self.gl_ctx.create_texture(), "Create GL texture")?;
        let raw = texture.as_ref();
        let id = raw.as_raw() as u32;

Great! Now, I want to use the u32 value to recreate the WebGLTexture so I can bind it. I really don't know how and I've tried many things. Any ideas? I can get as far as this, and I get a Reference(u32) object but I can't get to the final step using downcast or any other means.

       let a_ref = Reference::from_raw_unchecked(img_id as i32);

Thanks for any help you can provide.
