John Mark Bell 9aca901eb1 The convert stage of a content's state progression no longer reflows the content to the provided dimensions.
It is now defined as converting the content into a state in which it is ready for use.
The user of the content is now responsible for performing an initial reformat (sic) of the content before it can be redrawn.

Purge width/height parameters from hlcache_handle_retrieve/content_convert/*_convert APIs.
Fix up content handlers affected by the above change in semantics.
Ensure that browser_window_callback performs an initial reformat of its content.
