I removed GLEW, added glLoadGen (renamed to GL here), and added implementations for all platforms. Hopefully this goes better than GLAD did.
Fixed cmake for Windows
Fixed Windows goofy macros
Removed tools used to generate the GL headers/implementations as we never use them to build
Fixed signedness issue on GLX
Changed constness on passed argument, updated VC++ project files
Regenerated files
Merge branch 'alt-ogl-loader' of https://github.com/jp9000/obs-studio into alt-ogl-loader
Merge pull request #32 from jp9000/alt-ogl-loader

Alternative OGL loader. GLEW was bulky, slow, and sometimes didn't do its job that well. This is the replacement.
