Samplers and Textures

[bitblocks-dev]

I am currently working on a compute shader that takes in a heightmap and builds a mesh on the GPU, but I ran into an issue: bevy_app_compute doesn't support adding a sampler and texture-both of which are needed for my use case.

To clarify, I specifically need a way to add a Sampler and a way to add a TextureView.

I added the feature to my own fork of bevy_app_compute, but I am running into issues because I somehow need to access an Image from the asset server during the build step of my plugin, because bevy_app_compute workers must be made in the build step.

User code passes a Handle<Image> to my crate, then my crate uses world.get_resource::<Assets<Image>>().get(&heightmap_handle) where heightmap_handle is the Handle passed by the user to get the Image itself, which is then passed to the add_texture_view function of my custom fork of bevy_app_compute. Unfortunately, getting the Assets fails, likely because the asset is added asynchronously and therefore is not ready by the point I am building. I need to pass an Image (or rather, a &Image) because Image has the data, TextureDescriptor, and TextureViewDescriptor needed to create a Texture and create a TextureView from that Texture.

So far I have not found a solution to this predicament.
