Godot CRT Shader

for those who are going to use it in godot 4, just copy the "addons/crt_shader/CRTShader.shader" and add the following line along with the other variables: 

uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmap;

please make a version for godot 4

It's amazing 

This works great! Reminder to set the shaders as children of a canvas layer to get the effect following the camera.
