FT_LOAD_NO_SCALE means that all coordinates and distances are returned
in font units. For scalable formats, these are relative to the "EM"
size, found in face->units_per_EM
To compute the scaled values:
pix_value = character_pixel_size * distance / units_per_EM..
I was under the impression that this was pretty clear from the tutorial
and docs.. ??
