As you correctly state, the stroker doesn't increase the advance
width.  You have to do this by yourself.

Reason for not modifying the advance width is the non-linearity
between stroke thickness and advance width.  For example, you might
add a very slight `boldness' (say, 0.2px) to a glyph without wanting
to change the advance widths at all.

Please advise a patch to the documentation to make this clear.
