Sandro,

the intended semantics is as follows:
- with the "map" orientation the "above line" and others should work
as one would expect: the label should appear above the line
- using "line" orientation the "above line" actually means "on the
left side of the line" - so that in case of left-to-right line there
is no difference to "map" orientation, in case of right-to-left line
the meaning of above/below is reversed to "map" orientation.

Does that make sense to you?
