Michael Fabian 'Xaymar' Dirks 29bbe22bec obs/gs/effect: Preprocess shaders to improve platform compatibility 
Improves cross-platform compatibility of Shaders written for StreamFX through the use of preprocessing to make things a bit more compatible. While we don't perform any proper parsing, this will be able to prevent basic issues.
