Adds a new method to QgsGeometry for merging linestrings. By passing a multilinestring, any connected lines will be joined into single linestrings. Behind the scenes this uses GEOS' line merge. A corresponding expression function "line_merge" has also been added.
Updating the srs.db ------------------- The srs.db can be updated from the EPSG codes in the GDAL installation: 1) Install latest GDAL, be sure to configure with --with-python. 2) Set PATH and PYTHONDIR if installed GDAL in non-standard location. 3) Run 'scripts/qgis_srs.sh > new_srs.sql'. It may take a minute or two. 4) Run 'sqlite3 new_srs.db < new_srs.sql'.' 4) Run 'sqlite3 new_srs.db <postprocess_srs.sql' You can use sqlite3 to dump the contents from both srs.db and new_srs.db before you decide to commit.
