/**
* 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.
