Hi,
This patch fixes some bugs in emboldening.
The `strength' in FT_Outline_Embolden is halved so that, for example, a
vertical bar of width W will be, after emboldening, of width "W +
strength". And now it works as the documentation says.

* src/base/ftoutln.c (FT_Outline_Embolden): Strength should be halved.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default strength.
Don't increase slot->advance.y.
