How to set filters and address modes for loaded textures/samplers?

I've been searching for an answer to this for hours, and as far as I can tell, there is no example or project that shows how to do this, and it's not clear from the bevy code itself. I'm out of ideas at this point.

I started by looking at SamplerDescriptor, which has fields for setting AddressModes and FilterModes. A Texture has a SamplerDescriptor, so I could set it there in theory. But it's not so straightforward to access. Loading a texture the conventional way, using AssetServer::load, gives a Handle<Texture>, which doesn't dereference directly.

I could pass the handle to Assets<Texture>::get_mut to get a &mut Texture, but that only works once the texture has been loaded, which probably hasn't happened by the time I'd like to call it (immediately after load).

There's no way to figure out when the texture has loaded either. I tried looping on the value of AssetServer::get_load_state, but that seems to block progress, being stuck in an infinite Loading loop. There's also no obvious and_then that I could use to modify the texture immediately after it is loaded and before it is handed off to the registry.

So how then would I do it? Would I need to make my own AssetLoader wrapping something like an ImageTextureLoader? That doesn't seem like it would work either, I still couldn't get a reference to the created Texture object.

You can track Events<AssetEvent<Texture>>, which will send an event when your texture has loaded.

Ah ha, I thought there might be an event but I didn't look very closely at that. Thank you!
