How to correctly draw a line in Unity

Using GL Lines: I would recommend using the the GL API for drawing lines. The line thickness will always be 1px on screen and there is no option to change it. There will also be no shadows. The GL method calls are executed immediately so you need to make sure to call them after the camera has already rendered. Attaching the script to the camera and using Camera.OnPostRender() works good for render
