We were handling the STYLE tag getting added in the
dom_default_action_DOMSubtreeModified_cb callback, however,
the media attribute dadn't been added by that point.
We now check it in the dom_default_action_DOMNodeInserted_cb
callback, at which time the media attribute is available for
checking.
Note, we should probably store the media type in the
html_stylesheet structure, but for now we just have an
`unused` boolean.
Also, it may be possible to optimise to avoid parsing non-
screen media STYLE element data if we could detect the media
earlier.
Previously content handler debugging features were accessed by global
variables. This allows the setting of debugging parameters via a
content API giving per content control over debugging features.
Currently only used by the html content handler to toggle global
redraw debugging.
The frontends previously had to use an html renderer API to get the
encoding of a content. This also required the explicit checking of the
contents type rather than using the existing content API to abstract
this knowledge.
Keypresses now go via content interface.
Contents don't shove the selection object into browser windows any more.
Contents report selection existence by sending message.
HTML content keeps track of where selections in it exist.
Contents report whether they have input focus via caret setting msg.
Caret can be hidden (can still input/paste) or removed.
Consolidate textarea selection handling.
Make textarea report its selection status changes to client.
Various textarea fixes.
Changed how we decide when to clear selections, and give focus.
Remove stylesheet url globals -- the core will always use resource:{default,quirks,adblock}.css as appropriate
