At two places in FT_Outline_Decompose there is a division by 2 that
loses one bit of precision. A client walking manually through the
contours of a glyph and mapping the control points to floats by dividing
by 64 and then doing any required midpoint calculation for conics will
get different results

At two places in FT_Outline_Decompose there is a division by 2 that
loses one bit of precision. A client walking manually through the
contours of a glyph and mapping the control points to floats by
dividing by 64 and then doing any required midpoint calculation for
conics will get different results

Applied, thanks, with slight revisions (and formatting). Please
check.
