As far as I can tell, the self-alignment-interface functions are called
by Grob::try_callback_on_alist (grob.cc). The callback is actually run
by scm_call_1 so perhaps whatever magic (DECLARE_SCHEME_CALLBACK ?)
makes c++ procedures like aligned_on_x_parent available to scheme works
without including the header files in the c++ files that use scm_call_X.

This is just a guess though...
