Is your feature request related to a problem?

Allow changing the raySize of LivingEntity#rayTraceEntities This will never include Displays because Displays have a hitbox of 0.

Describe the solution you'd like.

Allowing the definition of the raySize so developers can include Displays.

Describe alternatives you've considered.

Requiring Spigot's long method

result = origin.getWorld().rayTraceEntities(origin.getEyeLocation(), location.getDirection(), 100, 1.0D, entity -> !entity.equals(origin));

Other

I told Spigot about this, and they're adding a JavaDoc to World#rayTraceEntities to tell developers to define the raySize for Displays. Rather than the method that inputs 0.0D for the raySize.

I think that we could introduce some sort of RayTraceBuilder, akin to the ParticleBuilder, to better streamline the process of ray tracing, rather than adding Yet Another Overload™️
