Description
The algorithm for translating SOLID entities fails on certain shapes. On the attached parallelogram, it creates invalid self-intersecting POLYGONs. On other SOLIDs with one or two distinct points, it returns empty POLYGONs.
In the attached patch, I have reimplemented the algorithm using a Jarvis march. The patch also fixes an unrelated crash that I was hitting in PrepareLineStyle.
