I have some crude plans to support native appearance in the CSS engine
somwhat related to [1]. This would be done through hooks, so the
respective native rendering functions (Win32/OSX/...) could be used
together with CSS-specified settings.

Being rather busy at $day_job there are no immediate plans to
implement this, but it could be used for "napkinleaf" custom
rendering, leveraging the theming infrastructure that the CSS engine
already provides (interfacing with gtk, system colors infrastructure,
widget matching, engine boilerplate code ...).

Let me know if there is interest, I'd be happy to help out or at least
discuss this in detail.

Optionally send a blizzard here, so I can't go skiing on the weekends.
