Renders a screen-aligned, distance-independent, resolution-independent, pixel-perfect quad in Unity. Use it with the built-in quad mesh. You don't have to rotate or scale the mesh renderer, the shader will take care of it.
Shader "FX/PixelDot"

Properties
{
[NoScaleOffset] _MainTex ("Texture", 2D) = "white" {}
_Color ("Color", Color) = (1, 1, 1, 1)
_Size ("Pixel Size", Range(1, 64)) = 1
