But that's beside the point though right? :)

I mean I couldn't ever envisage half the stuff that others seem to
require before I joined the LilyPond dev lists.

I guess the point here is if you have 2 points of reference it makes
it more flexible to align than just 1 and then you have manually tweak
it.

for example if you had a square box and you wanted the tick inside it
in 'naturally; (I'm using a silly example here) that you'd not want to
align the bottom of the tick but the place where Werner was talking
(i.e. the pit of the tick).
