Add St_Angle/St_azimuth function: St_Angle: Enter three point, which represent two intersecting lines. Returns the angle between these lines. Point 2 and point 1 represent the first line and point 2 and point 3 represent the second line. The angle between these lines is in radians, in the range [0, 2pi). The angle is measured clockwise from the first line to the second line. ` mysql> SELECT ST_Angle(ST_Point(1, 0),ST_Point(0, 0),ST_Point(0, 1)); +----------------------------------------------------------------------+ | st_angle(st_point(1.0, 0.0), st_point(0.0, 0.0), st_point(0.0, 1.0)) | +----------------------------------------------------------------------+ | 4.71238898038469 | +----------------------------------------------------------------------+ 1 row in set (0.04 sec) ` St_azimuth: Enter two point, and returns the azimuth of the line segment formed by points 1 and 2.
