Thanks a lot; I'll look at it closer soon.

Those bits aren't really undocumented; have a look at the
FT_CURVE_TAG_XXX macros in ftimage.h.  Consequently, your `switch'
statement isn't the correct solution; you should rather do a bitwise
comparison to check whether bit 0 or 1 is set.

Yes, the stroking algorithm constructs the outline from scratch; for
this reason, there are also much more points on it than on the
original outline.
