I have some problem with JS API 4.10
4.9 , GitHub - nickcam/FlareClusterLayer
require "esri/views/2d/engine/graphics/GFXObject", "esri/views/2d/engine/graphics/Projector"
But 4.10 without esri/views/2d/engine/*
Thank you Robert Scheitlin
Maybe I will tell the developer of flareclusterlayer update to 4.10 later
Actually I would like to know the difference between 4.9 and 4.10
It doesn't tell me about "engine/graphics/GFXObject" remove or move to which Class
