These use the offestSegment function to build and offset for a whole trail or expand a trail as though it was stroked with a particular line style. Still needed are documentation and an implementation of miter join.

Awesome! =D We will need to add a section to the user manual as well, just something to explain about the different functions that are available and what they do. |

Building on offsetSegment this allows us to produce the offset of a whole trail (offsetTrail) or path or to do symmetric offsets around a curve capped with an end style (expandTrail). Inside corners take a path that assume a symmetric offset. In the future we should offer several clipping options for these inside curves including clipping all intersections and clipping only local intersections (if the original curve has a self intersection the offset may also have a self intersection). Also not included are custom join and cap styles as these functions will need to change to take into account clipping.
