How do you find the difference between inner and outer window edges
with such a function?

I think the primary intention of the left/top frame parameters are
coordinates of the top-left corner of the title bar, because
x_set_offset basically sets the outer window's position to
f->left_pos, and f->top_pos.  That is also consistent with the
geometry specification.  In that case, the difference can be computed
from these frame parameters and the absolute coordinates of top-left
corner of the frame.

This is not reliable. Window managers may put decorations on the side, these should not be counted. Besides, left_pos and top_pos is not the corners of the title bar under X.
