Save / Restore window positions for different monitor layouts

[svargh]

Is your feature request related to a problem? Please describe.
I have 13' laptop and it is docked at home, undocked during travel and docked at work@office.
At both placing I have two 42" screens @100%scale or three 42" screens @100%scale.

Describe the solution you'd like
It would be nice after traveling to reposition all the window positions for a specific layout home/work.

I use already WindowsLayoutSnapshot (https://github.com/svargh/WindowsLayoutSnapshot) for many years
WIn11 also provides such feature, but doesn't work reliable when docking between eGPU at home and WDTB4 docking at work.

Describe alternatives you've considered
Working: For applications running on my desktop, I use WindowsLayoutSnapshot (https://github.com/svargh/WindowsLayoutSnapshot).

Not working: I tried using wmctrl based scripts and manually:

wmctrl -p -G -l 
0x01a00006  0 37656  2666 238  1063 908  inst-dev-company ~/save_window_conf.sh  — Kate

wmctrl -r 0x01a00006 -e 0,2666,238,1063,508

xpra places application windows where requested / where they were last mapped, it may clamp them to the display when multiple clients share the same session with different display sizes. Anything more fancy than this does not belong in xpra.

FYI: v6 will now restore windows on the same workspace they were last mapped on: https://github.com/orgs/Xpra-org/discussions/4055
