SDL_opengl.h isn't protected by magic incantations. You can just open it, 
and it's plain to see that it includes both gl.h and glu.h, but not glut.h 
(GLUT is mostly a toolkit anyway, which you don't need when using SDL).

Tesselate the sphere into individual polygons yourself, using basic 
trigonometric functions (sin and cos).
