[PATCH] Fix atom name used when clearing previous background Inherited from Fluxbox' bsetroot, the atom used to clean previous a previous background contains a typo: `_XROOTMAP_ID` instead of `_XROOTPMAP_ID`. This results in the cleaning never done, which I assume would leak the previous backgrounds.
Checking the Debian archive, only hsetroot, bsetroot, pcmanfm and spacefm are using `_XROOTMAP_ID`. They all seem to derive from bsetroot. On the other hand, many software are using `_XROOTPMAP_ID`, including xscreensaver and fvwm (both written at a time where people know how all this works).
