[Steve White]

Hi Khaled,

I agree as to a preference of cubic over quadratic splines, and also,
the conversion from cubic to quadratic splines loses information.

Both TrueType and OpenType are wrapper formats, that can contain
either cubic (Type1) or quadratic (TrueType) contours.

However some technologies (afaik) such as TrueType instructions, only
apply to quadratic contours.  I know from past experiments that in
some environments, this can make a big difference in display quality.

Either works well with current free-sofware technology. I'm now in the
process of testing Vista (again) and Windows 7, in which it's much
harder to get good quality.

For the future, I think only OpenType is moving forward though.  I'm
keeping TrueType primarily for older systems.
