Unreliable measurements

## Context

- Installed mesa3d.org's drivers: v. 23.0.3
- Tested on: Gnome (on Fedora)
- Laptop tested presented as follows by the vendor: _15.6-inch, FHD (1920 x 1080) 16:9 aspect ratio_.
- _Image size in full screen as measured with a **physical ruler**_ | Matches the size values reported by `xrandr` while running in session started on **X.org**; thus 34.4 cm x 19.3 cm (**15,529237982 inches**).

```
$ xrandr | grep ' connected'
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
```

Worth noting is the language abuse of the vendor, since rounding **15.53** to one decimal, makes **15.5** not **15.6**.

## Description

- Unreliable measurements for _x_ and _y_ axis under Wayland and X.org; as rule observed, _the higher the resolution is, the higher the measured values are_. Reported: _55,77 cm x 27,70 cm_.
- Identical measurements for _x_ and _y_ axis under Wayland and X.org, for a given resolution. That is at least an adequate behaviour.
