[PATCH 04/20] =?UTF-8?q?dix:=20fix=20comment, =20directions=20flagge?= d are 45°

[Peter Hutterer]

The two directions returned by this calculation are always the two boundary
conditions. Since we don't do quadrants but octants, the flagged ones are
45°, not 90°. e.g. an angle of 35° flags E and NE.
