* Generalized Polygon to edge interaction into db::Polygon tools
* Added tests for this
* Equipped region to edges interaction with this feature to
reduce random test fails
* Multiple (reproducible) seeds for Region tests
* More tolerances for TilingProcessor tests
* ICplxTrans is_unity? implementation is using proper
double tolerances now
* File watcher tests wait longer to allow for slow
response on loaded Windows build server
