It *is* definitely mandatory!

The way Esetroot does it is using two properties:

In summary:

_XROOTPMAP_ID is the pixmap to be displayed. ESETROOT_PMAP_ID is the
pixmap to be destroyed, if any. A program that quits after setting the
backdrop will set ESETROOT_PMAP_ID, otherwise it won't, so both types of
program are supported. So, you should only kill the owner of
ESETROOT_PMAP_ID, not _XROOTPMAP_ID in xfdesktop... Just like xfbd did.
