[postgis-devel] ST_Angle(P1, P2, P3, P4), clockwise or counterclockwise ?

[Rémi Cura]

Hey dear list,

here is a proposal for a new functiono ST_Angle
https://github.com/postgis/postgis/pull/97

Discussing this with @dbaston, it occured that maybe you would prefer to
have the angle counterclockwise (more a math rule) rather than
clockwise(more a GIS rule).

I choose clockwise because T_Azimuth already use clockwise.

It's an easy change, so please tell me what's the best.

Cheers,
Rémi-C
