Just a side note: In TrueType and OpenType fonts which use
second-order curves (contrary to third-order curves in PostScript
fonts), if you have two consecutive `off' points in the glyf table,
there is an implicit `on' point exactly in the middle between the two
`off' points.

I suggest that you use a font editor like FontForge to compare your
results with the actual glyph.
