Since gstvaapidisplay_glx.h do not expose gl.h/glx.h structures, it is not required to include them in the header. It is not also required to include them in gstvaapidisplay_glx.c, since gstvaapiutils_glx.h includes them and exposes their structures (e.g. GLXPixmap). Nonetheless, glext.h neither glxext.h are required to include, they are already included conditionally by gl.h and glx.h, respectively.
