Mipmapping is not adjusted while using the spyglass

When using the spyglass, the tops of blocks still look far away not loading their textures up close, but like this sheep the mob's texture do load up close.

Steps to Reproduce:

1. Create a grass flatworld
2. Get a spy glass
3. Set render distance to something high (like 20)
4. Use the spy glass on far away blocks

Expected Result:

The blocks would appear normally as they would when viewing them up close.

Observed Behavior:

The tops of the blocks appear blurry/"low fidelity" because of mipmapping.
