Wrong placement of tool spots in retouch when image is flipped or rotated
This bug was already reported for spot removal in 2.4 (bug #12267), but is still present in 2.6.
It is also affects the new retouch module (which is really great by the way - thanks!).
If you flip an image horizontally OR vertically than the position of the spot has an offset and it is not possible to place new ones exactly.
If you flip an image horizontally AND vertically than the position of the spot is correct.
Interesting is that the position where spot removal or heal are applied is correct - only the marked spot are wrong. You can see this clearly when you enable "show mask" (see screenshot)
