Good question!

Imagine that there is a notehead with a width smaller than epsilon.  We'd like 
to use it to position elements, but if skylines throw away anything with a 
width less than epsilon, the note head will not be part of the skyline and 
things will be positioned on top of it.

The concern before was a comment about numerical inaccuracy, but after having 
tested the patch, this seems not to be an issue.
