On line 357 in ftview.c, I think it is incorrect to double the
strength before it is added to the advance on line 376. To confirm
this I looked at the lines 895 and 959 in ftoutln.c. Indeed, each
outline point is moved by half the strength of emboldening resulting
in a total increase of the width by the strength value. So it easy to
fix in ftview.c on line 357, but much harder to propagate this sacred
knowledge to the higher level libraries.

The most recent snapshot from Toshiya-san, leads me to think that
outline.tags are not initialized
completely. Still looking ...
