4 space tab-stop is not the project standard?

The circle I moved does not represent a corner of the polygon. I just
moved it to make the line straight after the tabs.

I am sorry for taking your time for such a low priority problem, but
as we stumble across this, let me to make the change more clear.
According to git blame the tests with the shapes added by 04688df6.
The coordinates was written in the old format like this:

(3.0,3.0,1.0,1.0,3.0,0.0)

These are changed by 3d9584c9 to the new format like this:

(3.0,1.0),(3.0,3.0),(1.0,0.0)

In my opinion, the real intention of the first commit was to write
them in the new format like this:

(3.0,3.0),(1.0,1.0),(3.0,0.0)

It makes sense because the corners match the shape. So, I changed it
that way. If we will not going to change the tests, It would be okay
to just remove the shapes. I do not think they add more value to
the tests.
