Most of the formatting backend is demand-driven, so it's not always 
clear how much time an operation takes,

  obj->get_property ("direction")

may return a number directly, or trigger a complete (re)formatting of 
the entire score.


The time is probably spent in

System::pre_processing ()
System::post_processing ()

please experiment a bit with what would be useful.
