`GSPathSegment` `tangentAtTime_`

Is there a way to access that in python? From the header file I see that this method exists, but in Python it claims to not (while e.g. pointAtTime_ does).

I tried to workaround with performSelector_withObject_, too, but no success.

Why can I use pointAtTime_ but not tangentAtTime_, which is the one I need.

Works for me.

Yep, can confirm, in 3198 it works. I wrote this when using 3151, there it was not available yet as it seems. Sorry & Thanks!
