- New expression functions for area(geom), perimeter(geom), point_n(geom), start_point(geom), end_point(geom), make_point(x,y) - Add new variant to length() function which takes a geometry object, allows for length(geom) evaluation. - Rename x_at, y_at to $x_at, $y_at (alias old names) to reflect that these only work on current feature geometry - Add x(geom), y(geom) functions which return x and y coordinate for point geometries or centroid x/y for non-point geometries (fix #11008)
