HTML and CSS processing and layout
content -- fetching, caching, and converting content
Each URL is stored in a struct content. This structure contains a union with
fields for each type of data (HTML, CSS, images).
The content_* functions provide a general interface for handling these
structures. A content of a specified type is created using content_create(),
data is fed to it using content_process_data(), terminated by a call to
content_convert(), which converts the content into a structure which can be
displayed easily.
The cache stores this converted content. When content is retrieved from the
cache, content_revive() should result in content which can be displayed (eg. by
loading any images and styles required and updating pointers to them).
Code should not usually use the fetch_* and cache_* functions directly, except
for cache_free(). Instead use fetchcache(), which checks the cache for a url and
fetches, converts, and caches it if not present.
