- Potential fix for some crashing reported by John IV - Split color convolution and deconvergence into separate shaders for potential GPU savings down the line - Added light and heavy variants of the color convolution shader, the former with YIQ colorspace removed - Re-worked defocus to occur prior to shadow mask application, as it would be on a real monitor. - Removed Edge Detection, as it was just for fun and can easily be added in by users if desired. - Split "pincushion" into "Pincushion" and "Screen Curvature", the former affecting the only the displayed image and the latter only affecting the shadow mask.
