I found the problem after a couple hours of banging my head against the wall.

The Stem::width function uses Stem::flag to get the flag, whereas the stencil 
uses Stem::get_translated_flag.  Thus, the flag used for widths is not 
translated.  As the flag's bounding box in the font is shifted by a half stem 
length to the right of where the glyph actually is, and as the translated flag 
was always shifted by half a stem width, this is what made it work (albeit 

I'll work this into the patch tonight or tomorrow.
