Fixes the VariableBuffer segment buffer generation to avoid numerical precision issues at vertices with zero buffer distances. Also removes repeated points from generated buffers.
For a single vertex buffer distance = 0, the buffer narrows to a point at that vertex
If the vertex buffer distance = 0 at both ends of a input line segment, no buffer is generated around that segment
