* This is a very old repo, slang shaders have moved to libretro/slang-shaders
* This warp shader is already included in ShaderGlass, under RetroArch Library / warp category
* I tried all these three old ones nevertheless and they all imported fine for me, if you're still having trouble can you post a link directly to a .slangp or .slang which causes the hang, please; if a shader fails to compile there should be an error message so I will double-check that
