Lively Wallpaper 2.2.0.0

What's new in this version:

Grid Pause Algorithm:
- Replaced the default foreground window based pause detection with a grid based screen coverage algorithm - the screen is now divided into a grid (tiles), and intersection calculation is used to check if windows are visually covering the display

Solves several edge cases where the previous logic failed:
- Multiple windows (example: side by side), now correctly trigger pause
- Works even if a background window, not the foreground one, is covering the wallpaper
- Each display can now pause independently in per-display mode
- Reliable desktop detection
- To see the detection in real time, right-click the Lively tray icon and choose Report Bug ? Grid Detection Overlay
- Now when duplicate layout is selected all wallpapers are paused
- New All Process algorithm available in settings - scans all windows and check for fullscreen
- Note: Some performance related settings will be reset to default after this update

Animated WebP Support:
- Added support for animated WebP format
- WebP files are converted to WebM during import
- This is an initial experiment, planning on adding conversion support for more formats in the future
- Wallpaper customization is supported

Language Enhancements:
- Added custom language selection - preferred language can be selected from settings
- [Experimental] Language change applies instantly without requiring an app restart

Wallpaper Enhancements:
- Improved wallpaper import system: now copies wallpaper file(s) to the wallpaper library location instead of just referencing the original path
- Previously imported wallpapers remain unaffected - to migrate them, use the Edit option in library
- For wallpaper projects with multiple files, a confirmation dialog now shows the expected folder structure before importing
- From this version onward, newly imported wallpapers no longer depend on the original file - you can safely delete it without causing file not found errors
- Faster bulk imports: multiple media wallpapers are now imported faster by utilizing system thumbnail cache

WebView2 (Default):
- WebView2 is now the default browser engine for website wallpapers
- Since WebView2 comes pre-installed with Windows, the app no longer needs to bundle a browser engine, reducing the install size by ~50%
- Now website wallpapers supports H.264 media playback out of the box
