for Mono.WebBrowser. It currently includes a WebKit backend and
will in the future also include the existing Gecko backend (the
Mono.Mozilla namespace that currently resides on Mono.WebBrowser).
This code can't be in Mono.WebBrowser directly because the webkit
backend uses webkit-sharp and gtk, and 1) those libraries are not
yet available when Mono.WebBrowser is getting built and 2) this
avoids adding hard dependencies on winforms.
