Function rend3_gltf::util::texture_option_resolve

pub async fn texture_option_resolve<F: Future, T, E>(
    fut: Option<F>
) -> Result<Option<T>, E> where
    F: Future<Output = Result<Labeled<T>, E>>, 

Turns a Option<Future<Output = Result<Labeled<T>, E>>>> into a Future<Output = Result<Option<T>, E>>

This is a very specific transformation that shows up a lot when using load_image_cached.
