Tyler Goodlet e63cffaf53 Add `.xsh` script mentioned in gitea #50 
Note since it's actually `xonsh` code run with either,
- most pedantically: `xonsh ./snippets/calc_ppi.xsh`
- or relying on how shebang: `./snippets/calc_ppi.xsh`
  * an sheboom.

Tyler Goodlet 49bedb4912 Reorder imports in `qt_screen_info.py` ?? 
For wtv reason on nixos importing `pyqtgraph` first is causing `numpy`
to fail import?? No idea, but likely something to do with recent
`flake.nix`'s ld-lib-linking with `<nixpkgs>` marlarky?

Tyler Goodlet 35744f666f Add some Qt DPI extras to `qt_screen_info.py` 
- set `QT_USE_PHYSICAL_DPI='1'` env var for Qt6 high-DPI
  * we likely want to do this in `piker.ui` as well!
- move `pxr` calc from widget to per-screen in loop.
- add `unscaled_size` calc using `pxr * size`.
- switch from `.availableGeometry()` to `.geometry()` for full
  bounds.
- shorten output labels, add `!r` repr formatting
- add Qt6 DPI rounding policy TODO with doc links
