A balloon's `X-offset` property results in the following three alignments for a given x value.
x < 0: Balloon text
\
\
grob
x = 0: Balloon text
|
|
grob
x > 0: Balloon text
/
/
grob
This shows that `X-offset` controls the attach point alignment on both
sides of the annotation line, which is certainly a good default.
However, it isn't sufficient in crowded situations. What must I do to
get, for example,
Balloon text
/
/
grob
this alignment? Please advise.
