Hey Marc,
I unfortunately don't have much time to help you out, but I can tell you that
you are on the right track doing prints to the command line. I would not,
however, stash them in lambda functions used as overrides, as this can
sometimes interfere with pure properties.
There are a couple classic things I use, most of which are in grob.cc.
In Grob::pure_relative_y_coordinate, before the last return statement, you can
put:
if (name () == "BarLine") print ("RELATIVE COORDINATE for BARLINE at spanned
rank %d: %4.4f\n", spanned_rank_interval ()[LEFT], out);
You can put similar prints in the extent function (but this time printing the
two extent values).
Hopefully the difference will show up here.
Cheers,
MS
