Rajdeep Singh 3d51a994bf Address review: fix version check regression, warn only once ...

- Version check: revert to majorVersion() < 4 instead of checking for
  specifically 4.3. On macOS, init_ogl_context() caps to 4.1 core
  profile; compat shaders (attribute/varying) would fail in core
  contexts. The #version 150 modern shaders work fine on any 4.x.
  This also correctly handles future OpenGL 5+.
- Warning: use static guard so the message emits only once, even if
  compile_shaders() is called multiple times.
