[webkit-dev] help with porting

[Julien Sanchez]

Hello,

I'm interested too in such a port because I'm trying to render simple
html (no plugins or widgets) into image and pdf backends.
For the moment, I made a simple hack (inspired from Clutter project) to
render into a cairo surface. It works from the command line but it still
depends from X (and GTK) and I don't know where to begin to get rid of
these dependencies.
