* It is in one of the following states:
|
|
* CONTENT_FETCHING - the data is being fetched and/or converted
|
|
* for use by the browser
|
|
* CONTENT_READY - the content has been processed and is ready
|
|
* to display
|

* The converted data is stored in the cache, not the source data.

* Users of the structure are counted in use_count; when use_count = 0
|
