I have discovered some other minor optimisations to the stroker module,
but I'm not sure if it's worth mentioning them - they won't provide much
speed improvement but will get rid of some anomalies and inefficiencies.
I've been experimenting with a modified version of the stroker in
CartoType, in the expectation that FreeType's system is faster than my
own home-grown one (I don't know the answer to that yet). Map renderers
make very heavy use of strokers for road envelopes, and envelopes of
other linear features, and polygon borders.
Best regards,
Graham

Done, thanks.
