- fTools/polygon centroids: catch missing centroid with invalid geometry
(fixes#4963)
- fTools/validate geometry:
* fix final position of progress bar
* don't use isGeosValid()
* zoom to feature on locationless errors (including OTFR support)
* store/restore dialog position
- QgsGeometry(Validator):
* log GEOS exceptions
* (closed) rings need at least 4 points not 3
* log error when geometry can't be exported to GEOS
* don't produce "geometry is valid" error
- improve logging from threads
* keep message output from main thread as popup
* log message from threads to message log (fixes crash on python error
in thread)
- make geometry validation optional: none, QGIS and GEOS
- move internal validation to QgsGeometryValidator thread
- cache wkt in QgsCoordinateReferenceSystem
- fTools: leave progress of geometry validatation at 100%
- move coordinate capture to vector menu
