[Therion] smooth option details

[Stacho Mudrak]

Hi Rodrigo,

your detailed explanation is correct. Auto option can be useful, if bezier
curves are imported from somewhere - then smoothness turns automatically on
when the previous control point, line point and next control points are on
a straight line +-5 degrees.
