There are several ways. One fairly straightforward way would be for
a client that needed to create the pixmaps to open a second connection
and set it's close down mode to RetainPermanent. Then it should create
the appropriate pixmaps and put a property on the root window listing
the pixmaps.

Some care must be taken to avoid race conditions. Most likely, creation
and edition of the property will have to be done with the server grabbed.
Take care to observe the conventions for atom names.
