 In [changeset:"be2a0ffda5b08dca0d94c1498d84b62b83fe76f9/git" be2a0ff/git]:
 {{{#!CommitTicketReference repository="git"
 revision="be2a0ffda5b08dca0d94c1498d84b62b83fe76f9"
 Fix arc/arc distance to handle more cases such as contained,
 circular, and other interesting arc/arc alignments that come up rarely
 in ordinary GIS data.
 Fix compoundcurve distance calculations, in particular the
 containment test, which was failing for some cases.
 Replaced containment test with a ray casting algorithm
 that makes more sense for circularstrings that the
 winding order algorithm did.
