Changes in KiCad nightly coordinates and plot

[Salvador E. Tropea]

Hi All!

The last nightly run of my tests failed in a lot of places. According to
the logs it was 7.99.0-unknown-e536fa966c~172~ubuntu22.10.1

Not only the plots changed, but also the coordinates, as an example: I
export files in boardview using info from the PCB footprints from the
Python API and I'm getting tons of small rounding errors, like this:

-U25 3719 635 3847 521 912 1
+U25 3719 636 3847 521 912 1

Another example, the GenCAD export:

@@ -147,8 +147,8 @@

 SHEET "RefDes: C1, Value: C"

 COMPONENT "C2"

This is quite visible in the plots, I'm attaching a diff between the old
and the new image. Red means this pixel is different (more than 5% of
color difference).

Is this a glitch? Made on purpose?

I'm guessing this is https://gitlab.com/kicad/code/kicad/-/commit/c31b5eb7d8b89cc3e7630fa0550e3a911b1204a5 which was an intentional change.  The old numbers were more rounding errors than the new ones.
