[ft-devel] loss of precision in FT_Outline_Decompose

[Luiz Henrique de Figueiredo]

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 than one calling
FT_Outline_Decompose.

I was doing some tests generating outlines of fonts and come upon this
because the .eps I generated were slightly different but gave
apparently the same image.

Is this loss of precision a problem or will it never be seen in an image?
