How homogenous option solves a render artefact

This video shows how the standard calculation of the width point for the Advanced Outline produces a render artefact when the two width points are placed on different position over a bline.
Notice that the bline is a straight line and that the tangents of the central blinepoint are both zero. It is noticiable how the relative position of the width points changes depending on where are they placed on the bline although its relative value is always the same. The right width point (zero width) is placed plus 0.3 the left one. The animated one is the left one only.
When the interpolation crosses the central blinepoint there is a noticeable render artefact.
If the user selects the Homogeneous option for the widthpoints, the rendered width is not dependent of the position of the widthpoints on the bline, It only depends on the bline's length, as expected.

Very nice. Hopefully in future versions this will be the default, and the option will be to convert to nonhomogeneous (heterogeneous?)
