Add gizmo-crt shader (#413) * Add gizmo-crt shader This shader tries to reproduce a CRT-like output without replicating mask or RGB patterns. It has the following features: - allows fractional scaling - uses texture AA shader and subpixel scaling for evenly placed sharp pixels - has a horizontal blur function which mimics bad signal quality of some systems (megadrive, psx) - has a vertical blur function which mimics n64 vertical software blur - adds some noise to mimic restless CRT colors - has a curvator function - looks good with resolutions <= 1080p - has modest system requirements https://forums.libretro.com/t/gizmo-crt-shader/41409 https://github.com/gizmo98/gizmo-crt-shader
