that's a bit annyoing... isn't it
At the code level: what about graphics context: a ifdef for MAC, another for
WIN32, another one for Qt.... In fact an ifdef for each implementation.
Whereas if you were using Interfaces, you would only have to add (if needed)
a specific private member in your specific implementation.
So that's true that current 'platform' directory is good... but I think that
it could be greatly improved.

I know... but merging take a lot of time...
And I don't think that if I come on WebKit IRC or mailing list and I say "I
have a 5Mo patch which will break your architecture but improve it" they
will tell me "great, you are welcome" :p
I think we have to prove that our approach works and may be better than the
current one to hope seeing our approach being merged.
So our goal is not to do another fork of Webkit... If we can merge into the
trunk we would be really happy. Nonetheless I do not think that it will
happen in the next days...

WebKit/Gtk+ builds and runs fine on the N800. Integration work with
