FreeType normally returns coordinates to be multiples if 1/64th
pixels, called `26.6 fractional points'.

For `FT_Set_Char_Size', the horizontal and vertical resolution
parameters are integers (72 for your example), and the width and
height parameters must be given in 1/64th pixels (20*64).

If you really need integer coordinates, you have to divide all
coordinate values by 64 in the returned `FT_Outline' structure.

Maybe you can point out where the documentation fails to explain
this...
