WSL2->X410

Using this technique, linux apps (WSL2) can be piped to X410 Windows X-Server.

Windows:
- VBS script to execute/run a powershell without viewing a shell window.
- PS1 script to
  1) start X410 server if not already running
  2) get screen width of monitor
  3) execute linux script with optional possibility to pass parameter for hidpi settings
  
Linux:
- Optionally set HIDPI options
- Set DISPLAY env variable 
- Launch program 

Prerequisites:
X410: https://x410.dev/
WSL2

Caveats:
Screen width is not calculated correctly on hidpi resolutions/scales, e.g. 3840 results in 1920 with a dpi scaling of 2.
