web generator : glad_egl.h miss definitions from egl.h
Hi
glad_egl.h miss definitions for EGL 1.0 and forward.
i.e. unable to find things like  
# define EGL_NO_CONTEXT                    ((EGLContext)0)
# define EGL_NO_DISPLAY                    ((EGLDisplay)0)
# define EGL_NO_SURFACE                    ((EGLSurface)0)
# define EGL_PBUFFER_BIT                   0x0001
