> when i convert the to TT format i get a correct output
If Luigi is concerned with rounding errors, he shouldn't do that:
while the coordinates of the points on the curve wouldn't change, all
the control points would need to be recalculated due to the conversion
from cubic to quadratic splines. On the other hand, if you keep CFF
outlines and reset the units per em size from 2048 to 1000, you're of
course exposed to rounding errors, but all the original points are
retained, both points on the curve and control points -- thus it's much
less error-prone, in my opinion.
