I think that the reference point in X-axis is the left edge, while in
Y-axis it's the center.

Harm, i mentioned that in my opinion the optimal solution would be to
use core-extents.  Attached is a draft that introduces core-extent and
uses it for calculating stem attachment.  Unfortunately ledgers are
still wrong; it seems that it won't be that easy to get everything
working smoothly.
Please let me know if you have any problems with applying these patches.
