Werner, certain fonts contain glyphs with "isolated" points within
their outline (i.e. a contour made of a single point). These are never
rendered but they may have an influence on bounding box computation
(and in case you'd ask, the hinters already detect these cases)

I suspect this is to enable anchor positioning, especially for accents,
and it may explain the problem described here..

Hope this helps,
