Fixed phosphor gamut being applied when sRGB colour space is used Reorganised shader parameters to be more intuitive Moved base crt-sony-megatron.slngp into the shader directory to edge users away from using it directly Passed in texcoord to functions Added vertical center, vertical size, horizontal center, horizontal size, pin phase, pin amp Added gamm_correct.h for easier integration
