 * @Short_description: Manages aspects common to all #WebKitWebView<!-- -->s
 * @Title: WebKitWebContext
 *
 * The #WebKitWebContext manages all aspects common to all
 * #WebKitWebView<!-- -->s.
 *
 * You can define the #WebKitCacheModel and #WebKitProcessModel with
 * webkit_web_context_set_cache_model() and
 * webkit_web_context_set_process_model(), depending on the needs of
 * your application. You can access the #WebKitSecurityManager to specify
 * the behaviour of your application regarding security using
 * webkit_web_context_get_security_manager().
 *
 * It is also possible to change your preferred language or enable
 * spell checking, using webkit_web_context_set_preferred_languages(),
 * webkit_web_context_set_spell_checking_languages() and
 * webkit_web_context_set_spell_checking_enabled().
 *
 * You can use webkit_web_context_register_uri_scheme() to register
 * custom URI schemes, and manage several other settings.
 *
 * TLS certificate validation failure is now treated as a transport
 * error by default. To handle TLS failures differently, you can
 * connect to #WebKitWebView::load-failed-with-tls-errors.
 * Alternatively, you can use webkit_web_context_set_tls_errors_policy()
 * to set the policy %WEBKIT_TLS_ERRORS_POLICY_IGNORE; however, this is
 * not appropriate for Internet applications.
