//
// A CRT shader for the Windows Terminal.
//
// Default settings are for a readable but still stylized look.
//
// Trying to balance looks and performance.
// The film grain and flicker effects are very expensive,
// they require constant redraw of the terminal.
//
// A lot of this is probably not the best, as it is my first time writing HLSL.
// Also, I am not that great at math, and this was done under 4 hours.
//
// Originally based on "CRT Shader Effect for Windows Terminal" by Lorgar Horusov.
