Hi all,

Here is a patch to make embedding dillo into an X-window work.

tested with this FLTK program:

using namespace std;


int main( int argc_, char *argv_[] )

dw.resizable( &dw );
dw.show();
cout << "dw.xid = " << (unsigned long)fl_xid(&dw) << endl;

}

What does NOT work is automatic resizing of the embedded dillo window,
when the size is changed. This would be nice to have.
