The problem with negative coordinate values is partly fixed with my
relative coordinate patch (#991819). May be applying it could do half the
way to fix that problem.

By the way: Is there a reason that the group of patches to reach text
offsets (#991819, #993411, #993422) neither is applied to cvs nor anybody
writes which is wrong with them?  Do you think it is unimportant?
