[FEATURE] More geometry functions for expressions - add accessors: geometry_n, interior_ring_n - add num_geometries, num_rings, num_interior_rings - add nodes_to_points for converting every node in a geometry to a multipoint geometry - add segments_to_lines for converting every segment in a geometry to a multiline geometry nodes_to_points and segments_to_lines are intended for use with geometry generator symbology, eg to allow use of m and z values for nodes/lines with data defined symbology. 2015-12-15 07:39:43 +11:00			`{`
