[feature][expressions] Add "main_angle" function to return the estimated main angle of a geometry Returns the angle of the oriented minimum bounding box which covers the geometry value. Useful for data defined overrides in symbology of label expressions, e.g. to rotate labels to match the overall angle of a polygon, and similar for line pattern fills... 2020-07-14 10:31:27 +10:00			`{`
