-1 = #LEFT means align (the reference point) to the left border of the
text, 1 = #RIGHT means align to the right border of the text, 0 =
#CENTER means align to the center of the text.
#-5 extrapolates, so it puts the reference point two times the length of
the text (#RIGHT - #LEFT = 2) to the left of the text.

I'd probably rather use something like
\line { \hspace ... ... }
or \translate #'(... . ...) ...
myself. Then you can directly work with units of spacing rather than
jiggling with alignments.
