        Rubber-stamped by Ariya Hidayat.

        Fix compilation with the precompiled header.

        * WebKit_pch.h: Don't include JSDOMBinding.h and MathObject.h,
        as they include AtomicString.h. AtomicString.cpp needs to enable
        a #define before including AtomicString.h, which breaks if the PCH
        forces the inclusion beforehand.

        The default constructed values for QSize and WebCore::IntSize are different.  The former
        produces an invalid size whereas the latter produces a size of zero.  This was causing
        a layout to be triggered when constructing a view and an assert to be hit.  This patch fixes
        the crash by taking care not to cause an unnecessary layout triggered by ScrollView::setFixedLayoutSize.
