Still not good, i.e. getting these when quitting: Error Totblock: 4 new bpytriple len: 60 0x8889bdc ... 'cause nothing frees them.. Changed the loop that parsed input args to PyArg_ParseTuple to have support for passing ints from Python too as the floats that are the coordinates. Didn't find PyInt_AsFloat and figured that this is an ok way anyhow. Changed the default handle mode from AUTO to ALIGN, which is the same as in UI and more useful at least for me. Little sanifying in CurNurb (this was done with Ton).
