not clear what gladLoadGLLoader() returns
The landing page shows this signature at one point:

     void gladLoadGLLoader(GLADloadproc);

But in my generated glad.h for 4.6 I find this:

     GLAPI int gladLoadGLLoader(GLADloadproc);

Looking in the implementation in glad.c I get the idea this fctn is supposed to return true on success, but it returns false for me, and yet things seem to work (I would sort of expect everything to fail if that fctn does).  So I'm not sure what's going on exactly, could be my error for sure.
