 *
 * The protocol (0.5 version) is described at:
 * http://standards.freedesktop.org/xsettings-spec/xsettings-spec-0.5.html
 *
 * This code is greatly based on xsettings referent implementation I found on
 * freedesktop.org cvs, since specs are very unclear about the details.
 * Author of referent implementation is Owen Taylor.
