Screen space arrows

I want to learn how screen space arrows work, and I’m following Ricky Reusser’s guide[1].

I eventually want to draw a vector field instead of the bunny, but for learning how instancing and arrow drawing work, I used the bunny to match the guide.

Because the arrows are drawn in screen space (I’m guessing), the size of the arrows depends on the canvas resolution.
