Bug fix:
- Properly handle X server resources (pixmap atoms). Bug introduced with 0.7.0. Reported by and (hopefully) resolved with stharward.
Note:
Kill xwallpaper --daemon instances manually with pkill xwallpaper or a command like that before running xwallpaper --clear or another wallpaper setting utility. Right now the daemon process would still leak pixmaps as permanently retained if it is killed by another X client.
