A CRT shader that focuses more on simulating blur and blending effects and color levels of CRT screens rather than the physical attributes like phosphors and curvature. Highly configurable, can be really sharp, or really blurry or anywhere in between, with optional scanlines and contrast and gamma settings. Settings are stored in a separate "config.h" file for easy editing. GTU-Famicom is a variant that takes an image from an NES with "raw" colors and processes it to output a NTSC image much like an actual NES PPU.
The test program is a program that can adjust various attributes, such as horizontal and vertical blur, scanlines, etc. It is useful for testing settings to use with the shader, and also to understand how CRT shaders work in general.
