      * This is used to embed the tag cloud in other things.  New in version 7.
      *
      * It expects the url to be in the form:
      *   tag_cloud/embed/optionsbase/option1/value1/option2/value2/.../optionN/valueN
      * Where:
      *   optionsbase = "sidebar" or "wholecloud" (takes settings from this config)
      *   optionX = option name (either "maxtags" or any of the TagCanvas parameters - no name verification performed!)
      *   valueX = value of option (no value verification performed here!)
      * Here's how the tag cloud is built:
      * 1. Load "maxtags" and "options" variables for optionbase (as defined in admin menu or admin/advanced variables)
      *    Note: width and height are ignored, and the add tag form, wholecloud link, and inline tags are not shown.
      * 2. Use option/value pairs to override and/or append those loaded above.
      * 3. Build tag cloud, using 100% of the size from its parent.
      * Correspondingly, the optionsbase is required, but the options and values are not.
