Node graph editor basic demo for ImGui
// Creating a node graph editor for ImGui
// Quick demo, not production code! This is more of a demo of how to use ImGui to create custom stuff.
// Better version by @daniel_collin here https://gist.github.com/emoon/b8ff4b4ce4f1b43e79f2
// See https://github.com/ocornut/imgui/issues/306
