WlxOverlay-S v0.4.0

✨ :Important! ✨

• If you switched to pw-fallback due to No suitable device found error, chances are you can go back to (much faster) DMA-buf capture: rm ~/.config/wlxoverlay/conf.d/pw_fallback.yaml
• If you have a keyboard.yaml, you might want to put that aside and see the new defaults.
• Things are no longer relative to your head, but relative to the yellow "center" cross. You can re-center the cross using the Show/Hide binding (default: double-tap B or Y on left controller). You can also save your layout on the settings panel.

What's new:

• Introducing anchor: the center point for your overlays.
  • Displays as a yellow cross with label "Center"
  • Re-centers in front of you whenever Show/Hide binding is used
  • Overlays you place will be remembered relative to this point
• New save overlay layout button in settings panel
  • the last saved layout will persist through restarts
• OpenXR bindings are now read from a config file that you can change
  • wget -O ~/.config/wlxoverlay/openxr_actions.json5 https://github.com/galister/wlx-overlay-s/raw/main/src/backend/openxr/openxr_actions.json5
• Load keyboard layout automatically
• OpenXR playspace mover (thanks @RinLovesYou)
• PipeWire DMA-Buf support for X11 via picom (thanks @yshui)
