Build warnings

[0323pin]

Hi @woelper

Updating the NetBSD package and, of course doing a test build, I see the following:

warning: unused import: `RenderResult`
  --> src/image_loader.rs:13:40

    |                     help: remove this `mut`
    |
    = note: `#[warn(unused_mut)]` on by default

NetBSD is on Rust-1.74.1 but, on my machine (where this build was done) I'm using Rust-1.75.0
Leaving the warnings here just in case you haven't noticed them already.

Thank you so much!

This was an oversight on my end and is fixed already. Thank you for catching these early!

While rust is super strict about warnings, even an unused variable ends up one, so I still could not bring myself to treat warnings as errors. I'll probably make a new github actions check though!

Closing as complete.
