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
