Bug fixes:
- Release X server resources in daemon mode on resizing events
- Mark atoms as temporary to stay compatible with feh and hsetroot
- Added missing --focus option to zsh auto completion
Changed behaviour:
- Wallpapers on unspecified outputs are retained by default (queried from atoms)
New features:
- Added --clear option to remove set wallpapers, which also clears unspecified outputs
- Added --no-atoms option to retain wallpapers set in pseudo transparency atoms
- Added --no-root option to retain wallpaper in X root window
