I tried to align the middle point so many times, but the problem is that a 1px
point (or line, I had a crosshair in the middle first) doesn't seem to get
centered. If I use a 2px wide line, it is working. I tried so many combinations
of radius and such things, but it never fits perfectly.
Also note that the preview is not as precise, because it needs to interpolate
between reduced size and original image size. This can't be changed right now.
About the middle point: Maybe I'm missing something here. If somebody has an
idea how to fix it?
Also I noticed that different colors make the dot appear more in the middle, it
seems to be an optical illusion :-)
For example blue looks always better then red... well at least for me!
