There isn't really much high-level documentation available.

There are some basic diagrams of WebKit overall layout and WebKit/GTK+
class design in these slides:

The Cairo graphics backend used for all rendering including HTML
content, SVG and Canvas in the GTK+ port is in WebKit SVN. We have a
summary of the code modules (complete with links to the sources) in the
wiki:

The actual Cairo library isn't bundled with WebKit. You can download and
install this separately from http://www.cairographics.org/

You need Cairo 1.4 or newer and should ideally use the latest release.
