Behdad,
It might be faster, but then again it might not be, depending on the
value of n, the cost of the test for subdivision, and other things. I
shall leave all of ftsmooth untouched; this will be an independent piece
of software that may be connected to FreeType afterwards. However, I
shall not be engaging in a general discussion about this, except for the
odd question to Raph, but getting on with it, using my judgement as to
how to proceed - committee programming is not for me. Anyone who wants
to try other ways of converting what is a small piece of software can
try their hand; as I said, there's no rocket science involved.

Because it's faster to subdivide into n segments in a single loop.
But yeah, that doesn't really matter here, I think you can leave that
part of ftsmooth untouched.

Hi Werner,
yes, I e-mailed him yesterday, and asked a question about his code
too, but with no great hope of an early reply, knowing he's busy.
I asked him why his code to handle quadratic splines used a
division into a number of evenly spaced values for the t parameter
rather than recursive Casteljau splitting. The question was
triggered by seeing that there is a handler for quadratic splines
but not for cubics in his code (it was written for TrueType only).
I suspect the answer has to do with the use of floating-point
rather than integer arithmetic, but if there is no good reason I
will be tempted to (for now) use Casteljau splitting for cubic
splines, or for both types. I am almost certain that it will have
little impact on efficiency, or even improve it, but let's see.

Hello Graham,
I have started converting it to C++. I will do that for
now because
C would adds an extra layer of difficulty and slow the
work down;
but don't worry, there's no rocket science, and it should
be easy to
produce a C version when I've done it.
great! Please inform Raph also (in case you haven't done so);
I think
he is not on this list.
Wish me luck...
I do :-)
Werner
