SUMMARY
The vertical and horizontal mirror tools do not work with an odd number of
pixels. They kind of work, but they work sporadically.
I've seen related bugs, but they are all closed. I have seen this bug occurring
on the master branch, at the time of reporting, and it also occurs in version
5.2.
A short video of this may be seen at:

STEPS TO REPRODUCE
1. Create a 15 x 15 pixel image.
2. Turn on vertical and horizontal mirroring.
3. Ensure the mirroring is set around pixel 7.5 (for both width and height)
which is the middle of the image.
4. Experiment and observe that the mirroring is incorrect and unreliable.
