I notived the rotate filter does not say what way if being rotated. Clockwise or anti clockwise.
So i suggest adding this info.
is in degrees (right turned)
090Ã,° = anti clockwise
180Ã,° = upside down
270Ã,° = clockwise
I don't think degree says anything about direction.
always to the right until you are told otherwise.

The German translation has it. The filter is called "Drehen im Uhrzeigersinn" ("Rotate clockwise") there.
